It might not be to useful in lower keys but in high keys and in mythic raiding learning the barrier rescue talent is almost mandatory to keep us alive. Especially for devastation where it is one of our best defensive spells (same damage reduction as Hardened Scales but with a 1 min shorter cd). Having a group with all neural silencers, because they don’t want to get “interrupted” (which is fair) prevents us from using our best (for dev at least) defensive spell and wastes 2 Talent Points. Blizzard pls let us target ourselves with rescue so we can still get the barrier.
Aside from the part that your raid really shouldn’t be progging with neural silencer, twin guardian rescue is leagues worse than obsidian scales as a personal defensive.
This never happens to me, why are all of the people in your group using silencers?
Rescue doesn’t even interrupt.
That said, I don’t see a reason why we couldn’t self cast rescue from a logical standpoint, even if maybe it just has a longer cd when self cast to discourage solely using it on ourselves if that’s the issue.
so you aren’t just using it as a movement cooldown, would be my guess. but you still use it as a movement cooldown, you just drag someone else along for the ride.
Obsidian scales is better for predictive damage and lasts longer too. But when an Add randomly targets and leaves you at low health (15%) a barrier will mitigate more damage then Obsidian Scales and gives the healer more time to react.
