Aetherflow rework

Hello community! i have some ideas for the aetherflow skill, i find its concept to be very cool and i love play as summoner or scholar, but i think this skill would be awesome if SE change the way we get the stacks, its great that we have 3 stacks in 60 sec cooldown but in some situations i dont want to waste the MP recover from Aetherflow but i do want to use the stacks, for example: if i want to fester and my MP is 90% full i just waste the 10% of recovery just to use the stack, i know its better for me to wait my MP go below 80% to start using this skills or go to battle already with 3 stacks and Aetherflow out of cooldown, but i think we would have a lot more freedom to choose if SE split the skill in two parts,passive and active, in the passive effect of aetherflow we generate an stack automatically every 20 seconds as long as the skill is not on cooldown and the active we restore 20% MP as always, so we could spend stacks while saving MP restore more tough situations.

As a SMN (or SCH) you should never be running out of MP even with inefficient Aetherflow management unless you find yourself rezzing people multiple times in one fight, or you're soloing a fate for 8+ minutes.

That being said, you should also be using up more MP in one minute than Aetherflow can regen (except for certain trash mobs and then you just get your MP back between mobs anyway making Aetherflow unnecessary).
