My suggestion to mobility, what say you?

This I have an issue with, concerning the Rogue-class.
Not that warriors can own us in straight-up fights, not that mages/hunters/locks can kite us forever... Rather, an issue concerning how I belive Blizzard has failed in diversing the classes, especially in regards to armor.
Of course, what would be sweeter than giving Rogues the ability to wear Mail/Plate? Nothing you might say, but I rather like the fact that we are supposed to wear light armor that gives less protection IF we get something in return, and that ought to be mobility!

ISSUE:
Being the supposedly most versatile class concerning movement (Leatherwearing Light attack iirc from Blizzards description on class, which was the reason I rolled a rogue as my first toon) and having NOTHING to compete with in regard to warrior-movement unless you spec deep into Assassin (and who wouldn't trade the warriors movement-abilities for Fleet Footed?).

I honestly think we should have a trainable ability that resembles Fleet Footed speed increase and have the talent Fleet Footed get a buff for snare-resist (10->20% would be super, id love it) instead.

I mean, A platewearing maniac with a heavy 2-hander being just as fast as us + Intercept/intervene? Nonsense!

Clothies might complain that in that case they should get faster too as they are draped in cloth - but we are AGI not INT, so there, it should yield something when it comes to movement.

What say you folks?
