@CS,

That's all good in theory.

In actuality, 99% of the population wont' be getting COR rolls with a WAR in the party, nor fighting things that are 6 man onry. VWNM is alliance content, and the new Legion system will be multiple alliance content. People are having enough issues fill an alliance in voidwatch with all the different jobs, usually you end up leaving out one or two and just wing it. COR's just roll misers and tacticians, and not waste time on DA rolls.

In actuality, very few people will ever be anywhere near capping double attack. Caster centered Temper / Boost spells are ideal for a hybrid fighter mage as their the better suited to taking damage and the associated status ailments then your healers are.
