Only had 4 games, 2 first we won easily, 2 last were tough fights but the team gave in...making the team is critical, because you know your enemy beforehand, but you MUST have:
1)Tank
2)Physical DPS
3)AP
and it's great if the other two are jungler and assassin, but I've come to find that people hate all tanks except Rammus, who always gets banned first
Other than that, it's just a normal game, I've had my shining moments despite my average level.
