I understand now that it isn't the majority of my DPS anymore, but it is still one of the things I strive for, large numbers off a combustion. 524ilvl (40% crit) as my LFR geared mage at the moment with 2pc bonus. The highest I have gotten (with perfect RNG) was around 12k.
What has your highest combustion been post nerf? Still striving for a big one on Protectors.
