Thanks everyone for answering my questions before! I have another...

If you hit 80/80ish mana with both procs up, do you use one (since the mana cap is 100, there's some leeway before you waste mana) or do you just melee combo ASAP and overwrite a proc? If you use a proc, what do you cast with the Dualcast? Doing, for example, Fire > Thunder would mean you can't finish with Flare to possibly get your proc back, as it would unbalance mana (unless it was heavily skewed in the first place, but assuming roughly even). But Fire > Aero would possibly waste a proc regardless.

Thanks again.
