Quick rogue-specific tidbit from the second set of official Patch 5.2 hotfixes; this will only be relevant to PvPers:
Blind should now break on damage from Frozen Orb.
Frozen Orb is a Frost mage AoE damage-over-time ability (which also slows any enemies it hits, though that’s beside the point of this post). Some folks had reported that, in the wake of Patch 5.2, a player who was being crowd-controlled with Blind remained so even if s/he was hit with Frozen Orb while Blindeded (despite the ticking DoTs). That should no longer be the case.
Which, as @JDofAndersonia explains, is perfectly understandable:
@SvelteKumquat I'm blind! Someone shoot me with a spinning vortex of razor sharp ice! *thunk* Ahh, thank you. I can see again.—
