Everybody always wants to change setting of a class he usualy NOT plays.
Medics want panza to have less power. Or better : Disable panza
Engineers want medics to be less lethal. Or dont let them use medic packs for own use
But the setting, as they are, are appreciated by the players themselves.
We all have experience what it does to a server when we want to please a few people.
So, PLEASE leave all as is.
