It is generating threat but currently isn't displaying it as doing so with Threat-1.0Quote from
It seems the Hunter ability Mend Pet currently isn't handled, it appears to generate the same threat any healing spell would. (Testing with rank 1, which heals for 25/tick I needed 8 ticks to pull aggro when my pet had dealt 90 damage while in melee range, which is a very close margin to what I'd expect)
Should this not be generating threat? I'm confused.
Sorry for the unclear phrasing :)
