Help, Why do I lose aggro when healer cast regen?

[Kitru]

This will never happen. The enmity from all over-time skills is front loaded, meaning all enmity is generated at the time of casting and not over the duration.

Try doing a pull with Regen on you. Before you even get a chance to throw out *anything*, everything except for the target you hit with Tomahawk/Shield Lob is going to go running to the healer. Also, try having a tank swat a single target and then throw a DoT on it; you'll start off with barely any aggro and watch it slowly crawl up.

Effects over time most *definitely* generate aggro with each tick. They *might* be frontloaded (I have my doubts and it might actually be on a case-by-case basis for each ability), but, at best, it's 50% of total enmity upon application with the ticks generating 50% as much as otherwise.
