Heavy handed blanket nerfs will ruin the experience, it's much better to wait and see where PotD ends up being in regards to difficulty and go from there.I'd much rather they buff encounters then nerf everything to the ground.
That said, some things are way out of line like some swift flurry interactions, the brilliant inspiration, faith and conviction/deep faith etc.
On the other hand there are some high level abilities which are garbage (looking at you sacred immolation).
The thing I'm not quite sure on how they will get around to balancing (or if they will get around to balancing) is the fact that you can get some incredibly OP gear early on, personally I don't mind it being there but some might think it's another way to trivialize the game.
