After toying around with Dispersion in PVE and PVP, I’m starting to enjoy it a little more. I’d like to see it more viable in PVP with a few changes though.
In PVP, I typically keep the cooldown available for 3 things - Being kited, being beaten on by melee or being stuck in the middle of some heavy AoE battles.
Hunters love to kite. Its part of their class mechanic to kite. Apparently with 3.0 they all like to tame huge dinosaurs as well =\. During the Dispersion effect, I try to get as close to them as possible but I’m still vulnerable to Concussion Shot and other snare mechanics. Lame.
Since all Rogues get Cloak of Shadows and we have to spec in to Dispersion, I’d like to see Dispersion remove all debuffs and make us immune to snare/root/cc mechanics. It’s only a 6 second spell and it’s on a 3 minute cooldown but look at the nature of the spell. We disperse in to pure shadow energy - It doesn’t make sense that we still have DoTs, bleeds, snares, etc.
IMHO, Dispersion is purely a defensive spell to close the gap between you and the enemy or to survive a beating long enough for whatever is beating on you to be killed by your DoTs or other players.
Going against classes that can kite you from a distance (i.e. Frost Mages or Hunters) can be tricky as it is, but Dispersion (combined with Fade from Improved Shadowform) makes it easier to close the gap. Silence sure as hell helps as well.
In PVE I have no complaints at all. I usually blow it every 3 minutes for mana regen and so far I’m satisfied with it all around.. but I’d really like to see the change for it’s PVP use.
