If you have to go afk for longer than a round go into spectator mode. EU7 is full almost 24/7 and there is no place to leech.
I will unban you now, however, if it happens again expect the ban to be much longer and without an earlier unban. I'm guessing you are one of the chinese fellas that constantly play on EU server? Please do us all a favour and play on the chinese DTV, it's not there to be empty while you guys leech on EU with a horrific ping.
