I would stay away from a warrior. Instead I would recommend either:
Paladin: Insane dmg vs undead with the slay undead AA line, a fast cast strong root at 65, heals, hp and ac buffs and 90 % res.
Shadow Knight: Mortal Coil lifetap from weapon dmg, at higher levels ive seen SK's pull like 30 mobs at once its crazy to watch, feign death for when it goes bad, a little ***** pet think "pet dot", a snare line, a lot of ways to dmg a mob.
Ranger: Head shot AA at higher levels, Decimate humanoid mobs, snare line, nice atk buff lines, a lot of cool spells.
Warrior isn't a solo toon. The 3 above can solo a lot faster & better at higher levels with there class AA lines.
