Stop Citing Current Winrates - Stop equating correlation with causation.
There is not enough time/data for current winrates to suggest a causal link. If anything current winrate data is even more untrustworthy than usual largely due to the vast majority of players needing to be told what to spec their masteries to, how to play, and what to think. Until some established appeal to authority pro player comes out to tell them what to copy/paste all the current statistics are just another example of an age old saying. There are three kinds of lies; lies, damned lies, and statistics.
