I tought some classes already have limits?
Well since this isn't on all servers, Obviously yes, we need limits:
Scout: 4 at max, they are annoying in bad hands and annoyingly strong in good hands
Solider: Mayby 6-8, I really don't like those moments on vsh_military_area with 20 of them, Its such a pain
Pyro: 3 at max due to airblast, lunar knockback and flarejumping
Demo: 5, since we have Shieldcrit enabled in the right hands they can dominate everyone
Heavy: 5, Taunt-crit + proper aim= dead Hale, having 10 of them near most likely amplifiers and sentries can be very painful
Engineer: 3, like intented
Medi
3, like intented
Sniper: 3, annoying ranged fucks wich can climb walls etc
Spy: 5, Nobody really cares as their effectivness highly drops the lesser are left, mostly results in timewaste anyway
