The only thing I agree with is the damn Shove and pushing in general which has plagued the game since EA.
Even when I'm trying to use Thunderwave to just disengage from enemies, they get yeeted what looks like 60ft. to insta-kill chasms found everywhere. And then I have to reload to get the loot, or because my party getting insta-killed is just too annoying. The 5e push distance of Thunderwave is 10ft. Shove is 5ft. Those distances make sense and would cut 75% of the cheap instant kills.
Funnily enough, when I TRY to do an insta-kill yeet with Telekinesis, which costs a 5th level spell slot, it just fails. Bonus Action kills, 5th level spell does not. Seems a little backwards to me.
The raft fight before Grymforge has always been the most annoying offender. And they didn't bother changing it. Shove, Thunder arrow, insta-kill galore. If you're going to have insta-kill Bonus Actions in the game, you HAVE to provide means to defend against them. That means cutting the distances so that defensive positioning away from ledges actually does something.
