I often see comments like "if the DPS just lost like 500 HP I'll toss a regen", which is terrible.
Will just have to disagree slightly. Any being used wrongly will be classified as "MP" hungry. However; when looking at a straight Potency/MP efficiency, nothing in the WHM toolkit will best it - making Regen an incredible tool for incidental AoE damage against non-tank targets.

That being said, is it wasteful to Regen a DPS that took 500 damage? Probably - natural HP regeneration should handle that. However, if you have that "MUST HEAL!!!" OCD, Regen is the best spell to go to for those types of scenarios.

Random question of the day on the topic of natural HP regeneration - is natural HP regeneration in combat 2%/tick (the same as natural MP regeneration in combat)?
