"Riven is powerful right now, but she really doesn't seem to be near the strongest option in the game.
Frustration over her current state seems to be an especially western phenomenon. When considering power level, we look for trends that are consistent across regions."
It's past the year 2010. Everyone can look up statistics online. There's absolutely no reason for him to look at the stats himself, lie on Twitter that it is a "western phenomenon" and that he wants "trends that are more consistent across regions" when anyone with a brain could use the internet, the same thing people use to view what he said, to look at the statistics for themselves and see:
For ranks Diamond and above, **in all regions (globally):**
Riven's Winrate: 54.75%
Riven's Pickrate: 14.22%
For ranks Master and above, **in all regions (globally):**
Riven's Winrate: 57.89%
Riven's Pickrate: 13.71%.
Rioters should not willfully lie to the playerbase and should be held accountable.
