Mage damage shield potentially adding threat to caster.

[Balimon]

Any other mages out there find that our damage shield is adding to our threat? I haven't done any tests to see if the damage is counted as ours ( although I suspect that it is ), however I have noticed that when chaining a pet it takes quite some time for it to snap aggro.

When I don't cast damage shield, the pet picks up aggro right away. I've done some limiting testing so far and before I commit to a bunch of tests with logs etc I would like to see what other people's experiences are first.
