Agree with this.
Also for the comment above about the relic mage pet tanking dragons...yeah...well...it's a relic. It's not exactly a spell that will be easy to get for him.
Mage pet is a pretty good tank in most exp places especially the air pet. Mage+cleric is pretty good. Mage/Pally/Cleric pretty much unkillable imo. Granted the pally has quite a bit of overlap with the cleric as far as buffs go, but the healing + self-healing in that duo is amazing. Mage can summon dots and searfires for them as well. Good times. As often as the summoned cleric hammer procs I found searfire to be pretty sweet with that.
They lack crowd control...but with a tank and pet it's not gonna be needed often. and when it is later on...the pally has AOE aggro spells/stance to just eat up mob aggro.
