Merely a warning, but your statement on Blizzard liking to shaft melee DPS is pretty dangerously close to the point of infraction worthy whining.
Well honestly I feel, while ArP would be good for both trees(Combat and Sub) I do not see haste truly benefiting the Sub tree as much as Combat. The melee haste, minus the energy regen would be almost wasted on the Sub tree as auto attacks are so little of the damage. It seems a better fit for the "nukey" tree to have more punch on its attacks rather than auto attacking quicker.
As for Smoke Bomb I think a lot of us are scarred that it will change the way some boss encounters will have to be done. A rule in raiding seems to be making fights as simple for ranged dps as possible often shafting melee. I can only see this ability adding to this trend where it will be important for us to even stop dps to get up the Smoke Bomb for the ranged group.
