It would be nice if they would add some of the new game modes to the sortie rotation. It's nice that they've done that they've added some of the new missions from Zaramin/Sanctum to the steel path rotation and Omnia Fissures though.

Getting Dante is generally less grindy than some of the more recent frames especially with the pity system they added. It also came with some nice updates like better markers for Disruption and in a recent patch, made Rage/Hunter Adrenaline/Vex Armor usable even with overguard active.

From the time I've spent playing him, he feels mostly like a caster/Equinox with faster ramp-up and better survivability. I tend to play more weapon buff focus frames like Harrow/Wisp/Saryn with augments so Dante probably isn't really the frame for me. He isn't a bad choice though for anyone that likes caster style warframes/nukes though assuming you're fine with line of sight checks.

That would be Gyre with a Tennogen skin

Sorry about that, thought I had the URL in there. You also need to scroll down a bit to find the terminal.

No issues for me on desktop this time!

The Synth Scanner has always been like that. What you need to do to fix the particle trails is swap to a gun and aim down sights, then pull out the Synth Scanner again and the trails should update.

A good point to start is just running the daily public missions to get Primary/Secondary Arcanes, and the steel essence required to purchase adapters from Teshin.
Hildryn isn't a bad choice for steel path, Pillage is great for armor strip, she's very tanky and had some minor CC if you take her Blazing Pillage Augment. If you really want to use Hildryn for the infested, it might be worth putting Harrow's ability on her or the Rakta Dark Dagger to regenerate shields.

Equinox is kind of interesting having two frames in one.

Its passive could use a QOL update to match the recent change to equilibrium, allowing Equinox to pick up health orbs if its energy isn't full. I'd also like to be able to forma/mod the two forms independently (like Sevagoth) because of how energy hungry the night form is. Unfortunately, Equinox is a very RNG heavy farm, so it probably wouldn't be worth the extra time and resources to do this.

It would also be nice enemies with overguard were still effected by CC/Debuffs, but with diminished effectiveness, rather than the all or nothing approach.

If they're on PC, they can try clicking the settings cog on the launcher and verify their downloads cache. (No clue how to do this on console)

The only other thing I can think of checking is to make sure your Network Ports are set to different values if you're on the same network. Warframe will usually pester you if multiple people on the same network are using the same ports, so this probably isn't your issue, but you can find it under Settings > System > Network Ports. Any value is fine there as long as it is set to something different from the settings used for your game.

If you still run into issues, you might have to make a bug report on the forums to let them know that certain dynamic/interactable objects, like the hatches Zaramin, are indestructible while your partner is playing as a client. Still no clue what's going on with Lua but at least that one seems pretty minor because it's in a vault where only used for that mission and it's in the state for an alternate path rather than a state preventing completing the mission.

I'm guessing that you're playing as a squad, and that they are the Client while you're the Host. These sound like some issues with host vs client game states and were actually pretty common on the Zaramin at launch with the destructible objects hiding hidden paths, though I thought they fixed it there.

I have noticed that joining mid-mission into the new tileset that the grates aren't destructible for me. I'm guessing these were already destroyed before I loaded in and my game did not load their current state resulting in an unbreakable object. (was the same bug on the Zaramin, but I don't think it required loading in mid-game for them to be unbreakable for clients).

That last mission sounds like Lua Spy? Not too sure what's going on there, other than their game probably thinks something already triggered the chandelier to fall.

Have you tried to repeat any of this with your partner hosting and you being the client?

Ash is the damage orientated stealth frame and works great for dealing with high level enemies thanks to being able to Armor strip and Forced Slash procs. A couple drawbacks have been how hard it has been to acquire his parts, and inconsistency with his third ability activating, often only teleporting you to the target instead of opening the enemy to a finisher/performing a finisher with the augment.

The missions types that I like to use Ash for are Disruption and Survival, and while Ash works for Spy, there are other better options depending on how fast/easy you want to be on these missions.

Shuriken + Seeking Shuriken - A pretty basic ability and works great for quickly striping the armor off of important targets like Demolysts and Acolytes.

Smoke Screen + Smoke Shadow - The ability offer's great survivability, while I probably wouldn't bother with the Smoke Shadow augment. It might be useful for anyone trying to push a Kubrow to 50% crit chance for the Tenacious Bond bonus though.
*I think invisibility still prevents sentinels from attacking, so you're probably better off taking an animal based companion if you want a companion that does anything beyond being a vacuum in a mission.

Teleport + Fatal Teleport - Works great (*when it does work) with weapons that have Forced Slash procs on Finisher attacks like Rapiers. Unfortunately Mercy kills have priority over finisher kills, so if you were relying on this ability for gimmicks like charging the Arca Titron's Slam Capacitor, an enemy in Mercy Kill range will not provide a charge towards it. Enemies with Overguard are not opened to finisher attacks making this ability less useful.
With the current state of game balance around Overguard, I would probably remove this ability and replace it with Kullervo's Wrathful Advance, as this ability synergizes with Blade Storm's ability to quickly build 12x melee combo, and also provides teleport to Crosshair on hold which is very useful for bypassing lasers in Spy Vaults. Unfortunately I think this subsume has a high barrier to obtaining due to Kullervo being in Duviri and locked behind certain cycles.
Wrathful Advance Teleport

Blade Storm + Rising Storm - This ability generally works pretty good for clearing out groups of enemies thanks to its forced slash procs bypassing armor, mild CC, and quickly building combo for his third ability to scale off of. The augment provides both combo duration and increases the amount of combo gained/hit by Blade Storm, making 12x Heavy Attack builds more appealing.

From what I understand reading this thread, if instanceA goes down, any images hosted there are lost, while the comments will still exist because they're federated. You're only shifting the responsibility of hosting the image from a site like imgur to the home instance of the poster.

I guess it comes down to if you're concerned about how long your home instance is going to be around for, use an external host, or see if/when account migrations are added if images move too (although they would also have to fix the src for wherever the image is now being hosted)
