Speedrunning: Status Buffs and Aggro Management.

[Risvertasashi]

Generally healers should avoid regen spells unless really necessary.

Terrible advice. Regen increases HP/S throughput (Important in large pulls or just with heavy hitters), aside from being incredibly MP-efficient.

That said, yes, try to time it so it's off when the group dies. Of course, all the tank has to do is right click to take it off...
