[b]FB Optimal Gearset
This may be overly tangential assuming an exclusively ordinal focus on optimal gearsets, but I feel it's worth noting that FB spec can take the ideal FFB gearset, replace with , replace the 3 with 2 and 1 , and end up only 6 DPS behind the optimal FB gearset, which differs by 3 pieces - Heigan chest, Malygos belt, and T7.5 head - none of which an optimally geared FFB mage is likely to have picked up.
This point may be of interest to those who have already obtained the ideal FFB gearset and intend to switch to FB spec come 3.0.8, or to a more general audience given the nature of loot tables and RNG.
I just turned this around and ran the optimal fire set through rawr for a ffb spec with crit gems and sundial and you lose an amazing 4 dps compared to the optimal ffb set (although my dps value is 50 dps lower then enthorns for some reason). The difference is so small I can't imagine anybody actually switching those 3 items.
To the poster above me, Rawr can show you how much extra hit/crit/haste/spellpower/int and stuff increases your dps yes. I suppose those values could be included in the OP, but the entire purpose of Rawr is so you can work out what the best gear setup is you have available. So instead of calculating that with those general ratings they should just load up rawr and find the answer that way.
