But stuff like backstab giving advantage... I don't know if I mind? I know Jump is a little awkward right now because everyone's just bunnyhopping around the map, but I find the combat more fun than just running at an enemy and clicking on them. It's fun to have 2 bonus actions on a thief rogue. I love that fighters can throw people off cliffs and shit. The game is clearly balanced to make everything broken--casters get surface abuse, fighters get to backstab, rogues get to do whatever the hell they want. I think fighters probably got the worst of it which is where the complaints come from, but you toss in a totem barbarian that doesn't get affected by terrain effects or something and you've got yourself a crazy good time.
In my opinion, everything being broken is not D&D and is not really good game design.
