Getting rid of Flash would make the mobility problem even worse.

Flash is the only thing which lets champions without inbuilt blinks compete with those which do. Imagine if Annie or Galio had to walk up to the enemy team to ult them. They'd never land it ever. The people with blinks would just jump away as soon as they see them coming.

Get rid of Flash and you instantly make 60% of the cast unusable.
