Akali -- make the shroud more interesting

Akali has many problems. I'll talk about the shroud.

The shroud provides value early in lane, allowing Akali to apply some pressure and to cs. However, after 1 or 2 backs, the enemy laner will have a pink ward, which hard counters the shroud. Likewise, in any teamfight, any good opposing team will plop down a pink ward into the shroud making it entirely useless.

This is bad. Any entire ability should not be negated so completely so easily. On the other hand, there must be some sort of counterplay midgame or lategeame versus akali's shroud. This seems like a serious problem.

Here's my suggestion.

When inside the shroud, enemies can see inside the shroud but not outside. When outside the shroud, enemies cannot see in, and pink wards cannot ever provide vision inside the shroud for people outside the shroud. Akali maintains her 'invisibility' by ducking into the shroud when her target is outside of it and by ducking in when someone is outside of it. Her abilities and attacks do not reveal her to enemies outside the shroud when she is inside the shroud. Akali can dash into the shroud when outside the shroud by expending one of her ultimate charges. When dashing to the shroud, the range of her ultimate is greatly extended.

Of course this change would require other alterations to work with her kit (possibly changing how the 'q' stacks work to further back-end the damage, possibly straight nerfs to damage). However, this ability would be unique. And it would do many of the things that Riot says it wants to do with assassins:

1. it provides increased survivability without providing defensive stats.
2. it can allow for a more extended assassination by giving her increased survivability. Especially, she can use her q when inside the shroud, thus setting up her subsequent damage. If the 'q' ability were changed so that q's can stack, the damage of procing the first q could be reduced while greatly increasing the damage of procing 2-stack q or a 3-stack q. Enemies would know to either go into the shroud to find and kill her before she has stacked q's or would know to get away from the shroud.
3. it allows for counterplay at all stages of the game.
4. it allows her to contribute to her team without contributing damage or hard cc, thus she can be relevant even when behind.

Thoughts?
