Warlock Felguard Question

Hey yall,

I recently just started playing a warlock. So far I am really enjoying it with all the changes. I just unlocked my felguard and have a some questions…

  1. Can you teach it new abilities like other pets or is it stuck with the ones it has?
  2. Which is better for tanking while questing. The void walker or felguard?
  1. No

  2. Voidwalker is safer due to Sacrifice and being tankier. Felguard does more damage though.
