"Atretes Bar Darkon" is my Warrior/Necro. The Necromancer side of him is not all bad though, as when a group is in a hard press from Ettins, Tengu, and Muguuma, a quick cast (or a few quick casts) of "well of Blood" has saved the group many times.

It is always good to use "Life Siphon" and a parasite spell to weaken adversaries before and during attacks. It is important for the Warrior primary to remember that his primary function is to "Tank". That is, keep as many of the foe pounding on him, while the "Nukers" (elementalists) do their max-damage, and the Necro's raise up Bone fiends, horrors, and minions to do the light work of foe harassment, and the Monks heal and smite - Rangers should have already laid the traps and aggro'd the mobs.

The only one better at Tanking in the later game is the Monk, who can really take a licking and keep on ticking, if he has the right build and Elite skill.

For bringing new players through the early missions though, there is no better profession than a primary Warrior. With the Necro second, a level 16 Warrior is pure FUN back there.
