well...that's a general question based on the pt and your role
a general answer would be if it gave more mp while actively fighting than resting with a mph+ set then maybe that'd to me seem a bit illogical if you fight a mob and gain energy back than being in a resting stance. (this would be kickass solo vs. a mp mob)
considering that rdms dont rest much in general or in short spurts it's possible but coupled with the hasting, curing, debuffing, dispelling, the extra effort may actually hurt over time since you have to juggle a bit on rdm.
For no tp spam issues and mp concerns you'd need at least a ceremonial dagger, hornetneedle, or beestinger to make the most of it, if there was a en+mp spell coupled with hasting yourself for greatest return.
You could do it all but again the effort would be wasted imho, since the melee should be pilling through the mob like cookie dough and you removing silence, regening, keeping refresh order.
