Its pretty good. There are floods of medics on the servers now. Additionally, medics are far more gutsy than before; they're more willing to charge after you with the bonesaw. Gold Rush is pretty fun, unlike most attack / defend maps, I prefer attacking on it. The explosion at the end was cool the first time I saw it.
At least we won't have a problem finding a medic and people will be learning how to play medic by trying to unlock the achievements. This can only be good for players who wish they had a medic and one that can kill as well.
