In the hands of the right player, jugg is incredible... it's repeated aoe taunting allows you to maintain aggro while dps concentrates on nuking things one at a time without getting hurt. It also makes a great panic button. The OP room in elite tower with all the dogs that everyone complains one hits most warriors is cake with jugg. Vengeful is great for mana regen, but so is nexus and you can get another skill. The crit, strength, and damage from jugg still makes warriors inferior in dps to mages and rogues. Even if it was up 100% of the time, a warrior wouldn't come close to the dps that the other classes can dish out.
