My favorite things about BLM are flare and big numbers. My least favorite things about BLM are losing fire starter procs to double procs and spell speed being junk. I hope they buff those things.
I don't think BLM need more movement options. I like that it is "hard" to get off your spells in movement intensive fights. It feels good to finish a cast just in time to get out of the way of a bosses move. It would take away a lot from BLM if this aspect of the job was removed.
More decisions in the rotation would be a welcome change. It would be nice if fire 3 had a chance to proc an instant cast flare.

Oh and I almost forgot. please give every race 251 base piety at 50. Being locked into i90 crafted gloves because I am not one of two races is not a good feeling.
