I certainly don't think BLM are in need of buffs, but it would really be nice if they allowed firestarter procs to stack up to 2. It would help reduce the variance in BLM DPS and really improve the feel of the job overall.
For those who are unfamiliar with the Firestarter mechanic, 40% of your Fire I casts proc Firestarter which allows your next Fire III to be instant cast and cost no mana. The issue is that since you are chain casting Fire I during your Astral Fire phase, you don't receive the Firestarter proc until you are halfway through casting your next Fire I, which means if that cast of Fire I also causes a proc, you lose a proc. This makes BLM DPS even more RNG dependent than it already is.
Not only are you hoping for a 5% chance proc on Thundercloud, but you're also hoping for never getting back to back procs on your 40% chance Firestarter proc.
