Something I noticed is that the Jotun in The Wide Expanse, in Dredgehaunt Cliffs, may be some of the first Berserker Elite Specializations in the game.
They use Melee Torch off hand weapon.
Cant help but notice that they seem to do some sort of Dual Strike with it similar to 2hander weapon animation for Great Sword.
Maybe that has something to do with the leaked F2 skill on the Warrior in HoT.
