User blog comment:Lykrast/A suggestion about Flash/@comment-4022742-20130708082102

Might I make a suggestion of my own? (Gonna do it regardless)

If they'd give flash a small channel time like teleport only useable while moving, you'd have to counter it with hard CC but it'd still have the same function allround. You,d have to connect some sort of telegraph animation to it, so people dould respond to it.

Something like:
 * added 0.75 charge up time to use flash.
 * added second cast to use flash.
 * when not using flash 7 second after charging it, it goes into 21 second of cooldown.
 * summoner's insight reduces the charge up and cooldown timer by 33% (0.5 charge an 14 cooldown when not used)

This way you can't instantly use it, it remains a strong movement spell, it is more counterable then before, more noticable then before. It even adds a new layer of play because you could, fake out your flash or even delay it...
