Game Mechanics: Heaing aggro is bugged

[azxten]

I've generally noticed healing aggro seems "off" while leveling a cleric. Then lately I've been PLing and I noticed that I seem to "randomly" get aggro from healing.

The person I'm PLing can be at 0 health and I dump 500 health into them from superior healing and they have no other aggro than proximity. Two things happen intermittently:

1. The mob turns and attacks me. This seems normal. Healing generates some amount of aggro and it overcomes the proximity aggro the target had.

2. The mob acts as if nothing happened. I can immediately sit down after healing as well and not even that provokes the mob after a massive heal on a target with no aggro generated.

This should be easy to test. Just have someone get proximity aggro who is missing health, heal them, and repeat. Sometimes the mob will ignore the heal. I don't know if this is just healing aggro. I've tried testing LOS or anything else but it just seems "random" that on some occasions I get no aggro from casting a heal.
