Something I noticed for the first time yesterday in Coil is that if I activate Divine Seal during a pull (nothing else active, no regen, no target casting during the pull) it will generate instant aggro if the tank doesn't hit the boss first.

Tank pulled boss
I active Divine Seal without anything else active or active casting
Get instant aggro and die

That might or might not be the cause for other abilities of other classes too but that looks like a bug to me and is incredibly inconvenient.

Anyone else noticed this?
