I just became a lv 60 BLM a few days ago and after doing some EX dungeons, I have to say that it really is not very fun at all. Granted, I'm still inexperienced with the new rotation, but I think I'll stick to my SMN for now when it comes to casting.

The challenge of the BLM back in 2.XX was all the aoes you had to dodge ... now you have to deal with that while maintaining enochian. I feel like it's such a dps loss if you have to dodge aoes while trying to cast F4 but then have to B3 and then B4 to extend enochian.

While other jobs have timers to deal with, BLM probably has the strictest/ least forgiving due to the cast times of each spells + the 10s limit of F3 and then enochian
