Kil'Jaeden's trinket should be the tanking trinket and Archimonde's should be the DPS one.
I get what they were going for trying to match the fireball to the meteors in the KJ fight but he really should have the tanking one.
For one thing Archimonde is known as "The Destroyer" and for another back in the good ol' days Archy was a mage, Velen was a priest of course but KJ was a Vindicator (or at least that's the armor he wore.)
Anyway they represent the "holy trinity" of DPS, Heal, Tank but Blizz in their infinite wisdom has given the tank trinket to the DPS.
This offends me and I demand that they change it.
Well, not really, but it does kinda bug me enough to write about it.
