I haven't played since last year, and never very seriously but you're right about the community, it's not the best around. I tend to go back and play a few games from time to time, but it just doesn't keep my interest anymore. I think I mentioned it somewhere earlier in the thread, but Xin and Blitz were who I enjoyed playing most. I got decent with Zac, Heimerdinger, and a few others though.
I kind of played seriously for a while. Got really into it at a point, played almost daily, but that did not last for long. The community was the thing which seriously put me off. I did like Blitz a lot, as a support, though. I also thought it was quite funny that, whenever I had a really bad game and missed most of my hooks, if I land one really good hook at the end, everyone forgets all the bad stuff I've done. I have played Heimerdinger once or twice, not that much, but I did have a lot of fun with him.
And to be honest, playing league just doesn't keep my interest anymore either. Just can't bring myself to take it seriously now. It's really strange when I think about the fact that it seemed really important to me at a point in my life. Huh.
