I don't like it when teammates can't place a tower properly. It's a 3x3 and they think it's funny (
or apparently can't count) and place it one block off.
You tell them to remove it so you can replace it and nooo, you're the bad annoying guy ;-;
The Afker - what's more annoying than an afker? Someone who spams towers everywhere out of grid and then goes afk so you can't remove it and people won't let you vote kick them.
The one who is saving for the giant - sometimes you split the responsibilities, someone does the potions, upgrades and stuff while one teammate agrees on saving for a giant. I had this person on my team who said he would save up for the giant so at the end, he was just talking to us waiting for the money and once he said he got the money, he said "goodbye :p" and left without summoning it. So yeah, I'm sure there are other players similar which is so pissypissy. -
