I am also completely fine with our damage on the move. The mobility of casters is stupid, and I am glad for the fact that when they DO do their overhaul in the next expac and gut everyone's mobility, they won't even have to touch us. And at that point? We will be better than average, I'd wager.
What we do have for mobility isn't even all that bad. It is just different:
- SWP spamming.
- The option of FDCL for multitarget helterskelter, or Mindbender for a single target with heavy movement
- Divine Insight for helterskelter, such as Durumu.
- Shadowy Apparitions are still a factor often overlooked, especially since they have been fixed.
- Lvl 90 talents, obv.
The above toolkit, in a pre MoP world, would actually be considered a decently mobile class.
Also I think I see what your problem is. Your gear, while a decent ilvl, is largely healer gear. It is very light on baseline haste. Once you start to shift to a more haste heavy setup, you will see a huge difference.
I know I cringe every time I win a piece of gear that doesn't already have haste on it.
