Want me to proof it to you? I'll do it:
Kayle gameplay against Cho'Gath after level 6 Cho can't even touch a minion approx after 6 minutes
Kayle level 8 bullies Sion - no items just the AA range
Kayle (a lategame carry) 1v2's with just boots at 06:50 minutes
To top it all off:
You can find waaaaaaaaay more examples but I cba for some random redditor with 0 game knowledge. Now the question is will you swallow your pride and accept that you were wrong or will you rage and deny like a true league player?
