1v1 is ok only when you play -aa, -ai, -as. Just -ar or -ap is unbalanced.
And btw few days ago i played on Northrend server (official server) and cause i didnt care which bot i entered cause i didnt have any score, or will i play on that server soon again, so i got in one game and it was hard to get used to team play after pd.eu. But after some time suicide was a must. I go in make some mess and my team m8s kill what is left. I didnt care about geting high death ratio if i can give my team some time for a push.
