[Request] AST MP cost reductions please

[BillyKaplan]

Most of what people have said so far still rings like it needs to burn too many cooldowns just to maintain my mp. Lightspeed is an emergency button in my book and the mp cost cut on it ties in with what it should be used for, but it feels wrong to use it just for the sake of MP management. Burning Essential Dignity to get the cooldown on it down feels wasteful as well.
And nothing brought up in this thread negates the main point that AST's mp management is still locked heavily behind RNG, and many points brought up here are basically 'well if you get lucky it will all work out well'.

At the end of the day, the reality of the matter is that when I run BLM, it's the ASTs I have to Mana Shift before any other healer (used to be SCHs, but they changed them since), and that's in dungeons, raids, or the extremes I go into.
