Champion slump
I'm having a major issue with League lately. I play a champion for a while, do well, have a great kda (3+) but then after a while i seem to slump off and am lucky to break even. Recently it's been Amumu. I went from carrying games hard, nailing flash q's like a pro, getting lanes fed and a Pentakill 2 days ago to loosing every game I've played today and just can't seem to pull ahead.
But it's not just Amumu. I've done the same with Voli, Vlad , and Shacco . I don't get how players can have hundreds of games with a single champion and do well. I seem to be able to play a single champion for about 5-10 games before I start to suck. I could change champions and start doing well again, but I want to get consistently good with a champion before switching to another.
What do other players do to improve when they hit this slump? Do you stop playing that champ for a while? Do you keep trying knowing that when you can play poorly but learn from your mistakes you can be better? This is really frustrating (and it doesn't help when opposing team points out that you're having a terrible game).
