Unique Ways RDM can utilize it's Manameter

Yeah, RDM can Raise / Cure... but what-if:

-Certain Spells only were accessible via White or Black Meter Gauge, but also cost MP.

Here's my thought:

Haste: Party Wide 20% Increase to Auto Attack / Ability Recast / Spell Speed. Uses 1500 MP / 40 White Mana
-
Temper: Party Wide 20% Increase to Direct Hit Rate and Critical Hit Rate. Uses 1500 MP / 40 Black Meter
-
Regain: Party Wide HP / MP / TP Regeneration. 3500 MP / 60/60 White + Black
-
Would this be TOO much Utility? Or could this even work in FFXIV's perception of the RDM?

I want those... On WHM. And not with those numbers (it will hit HARD the healer balance). With temper, the WHM can have an equivalent of SCH's Chain Stratagem and with Regain the equivalent of BRD's Refresh.

And the haste effect could also add improved movement speed (such as Peloton does), to feel faster.
