I've been taking notes off of Feasel's Any% no reset for routing and paying attention to spell counts and such. I follow the importance of the double caster/double fighter for usability and survivability, I'm just curious what other comps are viable along with these strats? 

gyre seems to go with black mages instead of red mages, which i suppose would boost the potential spell damage output, but makes for less resistance on attack and hp pool.

Is the black mage damage gain worth it enough to offset the weaknesses? or does that run just become that much more risky?

Anyways, thanks for the responses/info, looking forward to trying my hand here.
