One thing to add:
Traitorous Influence in a lvl 10-19 warfront. LOOOOOOOOOOOOL
Seems we still have our lvl 50 abilities at low levels when using mentoring.
Necro pets are all doing far to much damage. I mentored down to lev 15 ad played around in Freemrach between Lakeside and Warden's Point. My pets all one hit the wolves and wild boars in that area which should not happen at lev 15. Makes it hard on the mage too, you have a harder time killing things and, staying alive but, you have to dismiss your pet because if you don't, it steals all your kills - you get no loot, no credit if for a quest and, cant,t even butcher the kills.
The pets' calin to have leveled down as well but their damage doesn't seem to. They seem to be doing lev 50 damage even if you mentor down with them.
