While I've made my share of complaints, I don't think anything in 5e is actually broken. I do think a few things are bent, and there a couple things I would have done differently.
But all in all, the game is perfectly playable, and enjoyably so, without a single change.
and some things get more bent based on play style, if the players control where and it to fight for example.
