My own mind about this new medic melee

Reduce the heal from damage to 5
Allow overheal (or set heal to 8 :/) it has real overdoes in it !
remove random crit (avoid kill before getting kill)
weapon deploy should be slower (to avoid naugthy hit'n'syringues)
reduce attack rate penality to -40% to avoid getting a "no anim" delay
