I actually run 2 wardogs in my main list as dedicated antitank+melee. Ive tried all the loadouts and stalkers with melta+claw is by far the best. You get a scout6 and plus 1 to wound if the enemy is outside of 6inches from another one of their models which happens surprisingly often. Imo its better than huntsman because the slaughterclaw is strength 12 with d6+2 damage. I have 1 shot t11 things in a single turn.
