Yep, when you crit hit a flare with Raging Strikes up it's pretty satisfying. No DPS can come close to the damage that can do (bar limit breaks of course).

Personally I have Raging Strikes, Quelling Strikes, Hawk's Eye, Virus and Physick as my 5 abilities although tbh I've never used Physick since BLM cures are terrible and I've not found anything resistant enough to warrant Hawk's Eye use.
