Interesting, I found it to be the opposite for me. It's incredibly tedious for me in Shield, but in Violet since I can send my pokemon out with R and just keep attacking wild pokemon without entering battle, it made grinding a lot easier for me. As a bonus, you get to farm pokemon materials for TMs.
I will say that raiding in Violet got worse after the DLC came out. There was definitely too many people hosting 1-3 star raids when they're easy to do solo, but I admit I was definitely one of those people too when I first started playing.
I mean they used to do this kind of stuff with the ATI chips from (now AMD) in the past, right? I vaguely remember seeing an ATI sticker on my GameCube or Wii
