If you knew how to check player's statistics you would understand why (besides him saying he did it)
Takes no more than 5 minutes (if you understand this stuff) to know which player cheated/exploited/wintraded and which didnt.
Nobody cares about statistics but they can tell more than most ppl know.
A little example: How many ppl with several rank 1 arena titles have 50ish% winning ratio only? (or less combined with alts) And thats just a very very very small example.
Why do you think everybody is butthurt just because they are complaining about something that was said by the person himself?
The guy openly admited cheating and ppl who complain are butthurts? I would be jelous of him if it were all legit but since it isnt I just cant, is not the way my gaming style works.
Please, have respect for ppl the same way we are having respect (or trying to) even when the guy is a cheater.
And 1 more thing... you should read the full thread (if you didnt already)
