There are good pieces of information throughout the mage forums in regards to specs, but one thing I haven't seemed to find anything about is what general crit percentage you would need in order for FFB or TTW specs to be viable. I'm currently playing arcane due to having a lower GS (5.6k), but I have 31% crit with molten armor. Would it be reasonable to think that somewhere in the ballpark range of 35% crit, I'd be able to spec back into FFB? I'm not exactly looking to break dps meters, so long as my dps remains similar and competitive, I'm happy. Arcane couldn't possibly be any more boring, not that FFB appears to be much more involving.
