It may sound like I'm just copying what tehnoob said but I'm a big fan of the game but since I'm always busy or being called away I never have the time to the play a decent match until it's late in the evening. Champions I tend to use are those you can get in the fight and can take a beating, tank or otherwise.
Some of us who are good and willing should form a RT team on it.
Play passive until he starts falling off. Most AD's will pass him about level 12, but until then he's just a bully with crab missles. Try to duck his acid canister too.
Akali is weak early game ios you can get in there and power her down. Then she is useless late game, just gotta be aggressive. I for one do not understand how to play kassadin. AT all. Any tips? (Note, I've only played him in 3v3 and dominion, to learn him but I just can't get the hang of it. )
its just really about denying, to defeat akali, and in general ap mids. When kassadin really you want to keep your farm up, an early w can help. But i use a q harass to keep people away and a e in close range wrecks.
I usually see Akali top and Blitz can counter her quite well (if you land blind hooks while she is invis) as well as Renek and Sion if your shield doesn't burst because of damage. And if she gets a little fed she falls off late game.
Love ten game losing streaks because of fucking retarded people who play this game. The worst thing about it being free is that morons can play it easily.
