First to Engage: Exploiting the mechanic?

[pasi]

NPC aggro is different here, so Giant tanking won't be possible.

First and foremost, NPCs will not hold aggro over players in melee range.
Second, charm NPC gives threat to their charmer.

Both of these make Giants not able to tank!

However, this mechanic does make it so casters don't really have to worry about aggro. I'm pretty bad at explaining this (I've tried to a couple times to pals), but here goes:

Say you have a warrior, an enchanter with a pet, a cleric, and a wizard.

You engage a mob, lets say Vorash since he keeps the tank stunned a good deal of the fight. Let's say our warrior is literally permanently stunned in melee range.

The charmed pet is whacking the fuck out of Vorash, the cleric is dropping CHeals left and right, and the wizard is dropping his load into Vorash too, but the warrior with 1 threat is still tanking. Why is this? Well, the pet is actually the one holding aggro here - Vorash just won't pick another target until a PC passes the pet in hate. But, since Vorash will not attack the pet with a PC in melee range, the warrior is effectively tanking despite having 1 threat. (This is how Liia and I do Vorash, btw!)

You can use this to your advantage to slow/debuff mobs without worrying about dying or moving the mob.
