he first Medic unlock, for example, is called the Overhealer. Instead of temporarily buffing people's health to 50% above their normal maximum, it permanently boosts them to double their standard health. The downside is that it'll be dramatically worse at building Ubercharge
Now that I like. It is going to add more strategy to the game. Take 2 medics on your side, one to uber you and one to boost everyone to 2x health.
Soldiers with 400 health FTW!
