Warlock tanks are able to abuse their Nemesis (draconic) 2 piece set, which lifetap their target’s health instead of their own, to get people’s HP down into fizzle range before sending a killing blow with an instant cast Searing Pain.
There is no recourse for this. The lifetap does not trigger CH guards. Trying to defend yourself however will.
If this is true, go have some fun with it. Warlocks deserve a little fun. 
I remember trolling a little bit with hummunculi early on in SoD. If it’s a serious problem, it’ll be fixed.
I haven’t heard that Homunculi was fixed to not have them running around like ADD kids, attacking players without triggering guard responses.
They just quietly removed the ability to even cast homunculi in a zone with guards.
Don’t worry we still can in most places my favorite was incursions. You would be able to solo wipe entires raids as a lv1
If only they’d just give them a pet bar…
Because I’m pretty sure the pet bar are really just spells that we cast that then apply an effect on the target (our pet) that directs the target to do an action/animation.
This would explain why if a hunter/lock had their pet on defensive and you attack it (obviously pvp enabled) the guards will attack you, but then also attack the pet (because the threat of the action is on the pet); kill the pet, and then attack you (because the pet’s attack as a reaction is counted like you casting the ability).
unless they fixed the hommoculi like since last week … i was using them in ch just getting people murdered by guards with no fault of their own lol as a gag.
really though that stuff is mean to do and i felt bad after lol.
