User blog comment:NinjaWolfy11/Discussion: What should be done about the mobility issue?/@comment-1601181-20120906002330

The best solution would just get rid of the most broken spell ingame, aka flash.

Thanks to flash, champions that are ok can become too strong:

Imagine Annie, no mobility but alot of damage, you know you have to stay away from her, you know she can kill you, and you stay away, hoever she flashes, does her combo and you die.

Or better yet, imagine champions with good mobility, like ahri and ezreal, thanks to flash they get an extra escape route even wenn they have the others on cooldown.

And like you said, champions with BIG teamfigh ultimates that require good positionig, become very easy to use thanks to flash(like malphite,galio,fiddlesticks in some situation, etc).

Altough many people would miss that spell, it would be the best solution for most ballancing issues.
