Campers. When playing legit I just hate them. Hiding in 1 spot with engineer/medic/assault is pathetic.
You said no hack related.. Well, I hate people who ruin a room with obvious hacks, even if they're in my team. Like opking for 9 rounds instead of just 1.. Whem me & my friend are just speeding/jumping for fun to mess with the snipers, or throwing some flashbangs with unl.ammo
What's the fun in seeing frag icons all over again every 5 seconds & most people exit..
