Personnally, I don't think Enochian is the problem, or the whole 3.0 BLM rotation. The main problem for us has always been mobility. Moving during a fight is at best a small dps loss, at worst a huge dps loss (loose Enochian and/or AF/HI). Having to move when casting I3 or I4 is a massive pain in the ass.

I would be really fine if we had a way to counter this drawback on our class, not all the time, but on most situations.

And this could be resolved by changing the CD of SwiftCast from 60 to 20 or 30 sec.

Still a CD long enough to not use it in a Rotation, but you become able, when needed, to move for 2 sec while not sacrificing dps (start moving > swiftcast > spell > land in your new spot and keep casting).
