Possible Cure/Non Interrupt exploit?

[Dashuto]

It's difficult to call this.

My math is horrible, but suppose someone was spamming Cure II alone an entire match: that would be 40,000 MP for them to cure 235k (Please keep in mind, 80 cap). For Medica II that would be 80,000+ MP. I think the first thing to look at may be: how are they getting the MP to cure this much? Even with abilities? I can attest there is not a bard supporting them with its PVP ability, nor are they using return as I've seen them at 0 deaths. (Does return restore mp?)
