User blog comment:Mineko Charat Lucky/I propose that Flash should really be reworked/@comment-6906412-20130811024404

Basically you are taking away a champion's mobility across the map but giving them flash instead. Zac, Shen, Lee Sin, Vi, Ezreal, Vayne (does this apply to Tumble?) Graves, and more lose a lot of mobility just to have the Flash active. Champions like Renekton, Tristana, and Graves no longer have flash due to the way that they use their dashes to clear waves faster or reposition in teamfights. Riven no longer has any sort of wall escape at all if her Q and E count as "dashes" (since jumping walls with Broken Wings is so incredibly difficult), same goes for Vayne. In essence, you are giving a champion without dashes/gapclosers the flash they need, but champions with any form of non-ult dash/gapcloser are severely limited in terms of their mobility if they want to have flash on a reasonable CD.

I would rather you remove flash completely than to have it reworked in this form. Flash exists as a method of clutch escapes or enages. Although I understand the problems with Flash mechanics in relation to champion kits (those with and without gapclosers/escapes), this rework simply isn't viable for most champions.
