Agreed on the polls, the ragepolling is almost every round now. Make it a bannable offense to poll without first giving a reason for it. That's kinda unrealistic, so if possible make it so it's only doable within the first minute of every round, same timespan as spawn window. At least it would keep it from popping up mid-battle, which is why it's so annoying.
But I teamwound and teambump a lot, relatively, and I've never gotten kicked by M yet. 5 chances is enough to cover even with rage reports.
