While I prefer the idea of reverting it, because it wasn't a problem in the first place except to you guys at Riot, who frankly aren't as in-touch with the game as much as tournament players who saw no issue, this is still good that you're accepting to change it. I'm interested to see how it turns out, but I hope if it doesn't turn out well once more maybe you'd consider just undoing it entirely.
Question, though - do you plan to do anything to make single-target junglers what they used to be; that is, just as viable as AoE junglers for different reasons? Because as it stands now, AoE is incredibly strong whereas people like Gangplank, Trundle, and Warwick suffer comparatively to Udyr or Skarner. As an avid jungler and someone who loves GP and Trundle, this was depressing to find out
Fiddle too, Fiddle is catastrophically weaker since every aspect of his jungling sucks with the new jungle (single-target nerf, high cost/low movespeed, ganks being less rewarding)
