Had an idea earlier, for a new trait for Healers (all of them, or just WHM specifically to give it a niche of its own):
Back From The Brink
Upon casting {Raise/Resurrection/Ascend/Egeiro} on an ally, ally is granted the status 'At The Brink' for 10s.
If the ally's HP is restored to Max before 'At The Brink' ends, 'At The Brink' is transformed into 'Back From The Brink'.
Back From The Brink effect: Upon expiration of this status, Weakness/Brink of Death's duration is halved.
In other words, if you do your job as a Healer, and quickly heal the player you just raised (instead of saying 'eh, OGCD regens will take care of it in time for the next raidwide'), the Weakness timer is reduced. It starts at 100s, subtract 10 for the 'did you heal in time' check, so that leaves 90s. Half of that, results in a Weakness/Brink timer of just 45s (plus having 10s of Weakness/Brink DURING the heal check), allowing the Healer player to make runs a lot more recoverable.
Numbers adjustable as required (eg maybe filling the HP to max in time reduces the duration by 30s instead of 45)
