Because it makes me not want to play Medic for awhile until I get used to them. Only using the applicator for rezzing is a scrub strat. Trying to see who needed topping off and who didn't was incredibly annoying when I played in a Bio Lab earlier. I'm sure the lower frame rate my aging computer is getting post patch wasn't helping things either.
Yes, because the health bar and the name/faction indicator is now the same color. The worst of it is that I can't even change it.
Trying to see a dark purple health bar at night is almost impossible. If there is no cross indicating low health I almost have to guess. For a while I even thought the health bars were gone entirely..
