Hello,
I guess with that change there will be less people playing medic, and server probaly will be more empty that it was before.
And you guys shoud consider, cause there will be less Medics to change the posion knive behavior, and able the heal from and medpack, so you dont need a medic from your team anymore.
IMO removing the abilty to heal is chaning the game mechanis complety i would have started with, increasing engi/fop to 130hp and disabling the selfheal from medic and the charge.
