Oracle/Calculator

I think these two could work with current gear set up from sch and whm.
implementing rotation would be challenging I imagine with CAL as to buffin or debuffing based on prime numbers or using a add,sub,mult,div wheel or gauge.
Could be interesting though.

Oracle would have to deviate from ast so it maybe using a different medium for attack and heals. im thinking a shout mech of some kind but not like brd singing mech.
