I see many good ideas here to fix BLM here and i hope SE will read some and maybe use them.

Atm, i must say, BLM is a dying job.
Myself, i recently switched to RDM and even if im still learning the job, i must say: OMG, i feel so free now! Playing a job with flexibility and utility change everything.

I dont even see the point of playing BLM again: My group hate when im on BLM cuz they have to adapt to the turret position, i have no utility and despite the punishing rotation, there is no reward at the end.
With some practise on RDM im 100% sure i will have about the same DPS but without the punishing rotation and with utility.

So yes, BLM need some serious fix and its not only a question of DPS gain.
