Please note: this feedback will mostly be focused from my own perspective as a forever GM. I am less concerned with how powerful X is against Y, as I am for the health of the game, and the ease of running encounters.

During my playtests I was given the opportunity to see both a Rogue and a Ranger, and they both feel good and bad in opposite and complementary ways. In short, the Rogue is fun but a breakdown of damage spreadsheets reveal it’s in a bad spot. In contrast, the Ranger has a lot of moments that detract from its fun, but joyless math shows that it’s super-effective.

Rogues are affable & attractive idiots

For the rogue’s part, being able to tactically choose what cunning strike to use at each given moment allowed for ranged rogues to opt into a controller role in combat, making one enemy’s life hell for a turn. When this works, it feels amazing as you are able to severely hamstring or simply exclude opponents from contributing at all on their turns. Unexpectedly, the Trip Attack with the Light Crossbow Weapon mastery allowed the rogue to make enemy melee bruisers get nailed to the ground, with a net -20 to their next movement due to being slowed, and having to use half of their reduced movement to stand up. This forced enemies to default to the party frontliner when able, or to use their action to dash instead of doing anything useful in the turn.

However, their damage is quite low. The player didn’t really notice this at the time, but a look at their output showed that they were not really big contributors to damage, and there were circumstances where their Cunning Strikes really didn’t have any impact on enemies.

The Ranger is a high performance hot mess

As for Rangers, they have so many problems that just amount to their spells all requiring concentration. There are so many toys that a Ranger simply can’t access because it would mess with their attempts at optimal damage output, and the mechanisms of bonus action to cast, concentrate, and then hit to apply the riders feels quite outdated, especially compared to the treatment that the Smite Spells received in this playtest.

However they were the number 1 damage dealer at the table. Honestly I think it’s too much damage for a ranged class, particularly because my Hunter-Ranger optimized around getting 60 movement speed, and getting the ‘Hunter’s Leap’ level 7 subclass feature. I simply couldn’t get them in melee because of how elusive they are, using their reaction the moment an enemy closed to engage them, prior to me being able to put attack actions onto them.

But this puts the dev team in a strange spot. If they fix how mutually exclusive all their damage increasing spells are, their damage output will skyrocket to preposterous levels. The solution is one that will be unpopular: Lower ranger damage quite a bit.

Additionally, a raise to rogue's damage should be performed, particularly in Tier 2-4. Maybe increase the number of die they get starting at level 5, 11, etc, or increase the size of their sneak attack dies at those places.

Finally, people who think that the new Hunter’s Mark is a nerf really need to actually give it a shot, because this feels much better.
