Well, i hate everyone and and no one particular.
But there are some types of players, which i hate more than the rest.
#1 feint spammers. Maybe they think it lokks fancy, but for me it is just boring. Most of the time they are quite fast as well, so i could not get out of their range that easily to try another attack.
#2 more siege specific, through the door hitter. Quite lame and annoying, but hey everyone does it, even admins. And my mommy told me, it is okay to jump off the bridge/cliff if the others do it, too.
#3 siege specific as well, the round is over kill hunters. The k/d ration of he siege is not tracked and one of the sides has won already, so it does not matter if you kill one or two more.
#4 the i want to say hello kickers. There is a chat and i can read, there is no need to drain my hp.
