Its basically the opposite of this forum, where everyone just hates on the game constantly for everything, as if there's absolutely nothing good about it. At least on reddit you get a bit of both.
Check the accuracy stats for most pro's and you'll see that every season they're within 1-3% accuracy of the previous one since August or longer.

I'm not saying heavy aiming isn't a thing, just that its not creating hugely inconsistent stats. These guys play hundreds of games each season, and their accuracy stays within 1%.
