People are toxic because its a team game and they don't want someone to throw away 'their win'
happens in most competitive team games, especially when ranking is involved
(being called a hacker is a compliment, as long as you aren't hacking, not sure why people view it as a bad thing)
also accidentally bought a nova when my team was supposed to hard save, went to defend B on Dust 2 and got a triple headshot when they ran in
that was the only time they ever went B site and they never did it again (unfortunately for me and my low score)
also I think the friend I queued with was wallhacking, should probably remove him
