Cool, I was just having a rough time lately. My favorite champions are Aatrox and Braum by a mile! And with Braum, I could get away with building nothing but tanky items and adjusting to whatever items I was being hit with first. With Aatrox, I'm told I should rush BORK.
But after getting BORK, I'm lost usually thinking I should get boots that could help me win more, or get boots that gimme a defensive stat. Maybe Another defensive item. Then another attack damage/speed/or lifesteal item. And then... everything else after that is kinda a mess of buying more attack damage because we're winning and I've won my lane. OR buying more tanky items because we're loosing, or my lane is looking ROUGH.
I think I'm thinking in the right direction, but I'm still unsure because I don't get any feedback usually.
I figured a good way to start off with a champion is checking out what they scale well with and then adjusting your build better according to those things.
It's just really rough going back into lane against a champion that's going to blow me up and I have to play close to the tower the entire time I'm in top lane because they're super aggressive and sooner or later, they WILL call for a gank and kill me under my tower.
BTW: I really like your lengthy detailed response by the way. It shows you that you know. +5 points for Knowledge
