Darth invader is such a great name haha. And wow, beta. I think I started mid season 2? I don't quite remember. I like to think that if I really tried to rank up I could get to at least gold, but that's how most bronzies feel. I suck so bad with lee...I think its the two-skills per button thing that is so different from the more auto attack based champs I enjoy that makes me misplay him so much.
I changed it to that about half a year ago, because I was tired of my old name. If you're only playing this long, you will improve for sure. Just don't let your mood get ruined by some random soloQ teammates. The two-skills per button thing on Lee is also a problem for me, but a totally different one than yours. I get bored really fast when I play champions other than Lee because i just get the feel that i could do a lot more with 7 skills instead of 4. That's also why I started to play a bit of LeBlanc, because she also has 5/6 skills and the juking possibilities with her are just insane.
