Healing in Killing Floor 2 has always been very interesting to me because while the game is technically playable without a medic, the healing it provides is so powerful that you really want to have a medic on the team. The class also gets some fairly powerful and varied options for guns. With shotgun, AR, SMG , starting pistol and healing grenade you have surprisingly varied lineup within your medic weapons to fight against the zombies of the game. A bit of a jack of all trades in terms of guns with much higher healing than other classes and a very powerful buff on top.
