Several existing conditions are now just, functionally "Skip your turn", instead of the interesting and varied things that they were which made taking your turn more challenging or something you had to think about. This is bad for any game, and it's not fun.
Prone is the worst example for me, because currently Prone inflicts Unconscious - which is why it skips your action and ends your concentration.
This is absolutely true as well. I wasn't thinking about the sameness of it all but you make a good point here.
