User blog comment:Lykrast/A suggestion about Flash/@comment-3529572-20130707064330

I agree that Flash is too common as a summoner spell (8/10 have it in every game), but giving a full DotA treatment for Flash isn't a good idea imo. Unfortunately the whole game is balanced around every single player picking up Flash to have an escape ability, and a drastic nerf to its escape strenght would screw up balance in the entire game.

I've been thinking about a similar change, which still keeps it as an escape ability, though less effective: range is similar, but if you took champion/turret/bigmonster damage in the last 2-4s, the range is reduced (about that range, which allows you to jump through the small walls - around bluebuff, dragon/baron pit).
