LoL is a blast. I suck at it, but I still have a ton of fun.
Fave characters are Cho'gath, Ashe, Garen, Swain, Kog'maw, and Vlad.
I'm saving up IP for Kog'maw and Vlad right now, but I'm not even level 30.
I'm a noob, but I don't do too bad. Generally 50/50 or better in my matches won/lost. For anyone who wants to play wit' me, my tag is brningpyre.
We could also include other DoTA games in this thread, like Heroes of Newearth. I don't play 'em, but I know a lot of people do.
I would save up some IP for good runes. It can really turn a game around. Get movement speed quints, and mana regen per level / 5 yellows. The movement speed quints are expensive, but amazing.
I'm saving up my IP on my noob account so I can get a full crit page for Tryn when I hit lv 20, then proceed to rape.
Also I'll add u ingame. Don't care if you suck.
Edit: Concerning movement speed... I think it's fairly underrated. How many times have you died because you were JUST BARELY too slow, or you were one auto attack away from getting a kill, but you were too slow.
I've started running 1/12/17 on almost every champ unless they're a straight caster. 1 point in crit, 12 defense with a point in nimbleness, and in the utility tree I get 3 points in quickness and 1 in flash.
I take flash on almost everyone because it's just too easy for getting away.
And for my starting items I often get boots and 3 health pots. This isn't that viable in higher elo, but it's just too much fun when you have 370+ movement speed at level 1... It makes harassing and getting away from early ganks so much easier.
