Advantages
Lurtz is a very powerful and cheap Hero for Isengard. You can recruit him quite fast and get him to kill a lot of units from afar. He deals quite a lot of damage, especially when he levels up. His Cripple can help you keep a distance from strong enemy heroes while you shoot them from a distance. His Leadership also can benefit Archers, which can help you clear out forces quickly.

Disadvantages
His Carnage ability has quite the cooldown, so you won't be able to use it as much as Cripple. When he is using his sword, use it sparely. In addition, make sure there aren't a lot of enemies around while he is alone. Even though he can escape Heroes, he might escape fully upgraded cavalry. Also his melee-attack is quite slow, ranged attack deals low damage at earlier levels and this can cause trouble on earlier levels.
