Rehgar Earthfury has seen his share of combat, both as a gladiator, and a master of his own team of fighters. Now, having put that life aside, he serves as a simple shaman of the Earthen Ring, earning his redemption by healing the broken lands of Azeroth.
Instead of using a mount, you transform into a Ghost Wolf with 20% increased Movement Speed. Basic Attacks in Ghost Wolf form cause you to lunge at your target and deal 75% bonus damage. Dealing damage, using Abilities, and channeling cancels Ghost Wolf form.
Being a more aggressive Support, Rehgar can reliably keep The Butcher alive and provide additional damage to his targets. Lightning Shield is good for extra bits of damage, and also aids in waveclear, which is important when The Butcher is gathering Fresh Meat, while Earthbind Totem is useful to prevent opponents from fleeing, especially when they have been marked with Butcher's Brand. Lastly, Bloodlust greatly boosts The Butcher performance.
Similarly to Uther, Rehgar is a strong healer, and has the right tools to complement Li Li's set. His Lightning Shield can be used in conjuntion with Cloud Serpent on Warriors and Melee Assassins to improve their trading ability, while Earthbind Totem works fantastically with Water Dragon, especially if Earthgrasp Totem is taken, allowing for a massive slow chain.
