At last we want to reiterate that the Felhunter just felt like a jack-of-all-trades 2moons gold PvP pet. One of the things we're trying to do with Warlocks are get more of the demons feeling useful. The Void alker gets used a lot while leveling and then gets parked, even though it is one of the more - perhaps the most - iconic pets. A passive buff is something we'll consider though.
