keterys or deathdonut why don't one of you guys try a Goblin Warg Cavalry, to me it's one of the more iconic images of fantasy.
Have a few abilities like
Coward's Reward - If a Goblin Warg Cavalry attacks from behind (has combat advantage) the rider deals an extra 2d6 damage.
You killed my rider, prepare to die - If the Goblin rider is killed the Warg goes into a frenzy automatically striking all adjacent enemies and getting +2 attack +5 damage for rest of encounter....(if both creatures were put together into one block this could be a bloodied reaction for the loss of Goblin attacks)
Knock, Knock.....I'm a Warg....auto trip - Warg attack does damage and knocks opponent which the Warg portion has combat advantage on prone.
The Charge of the Fuzzy Green Brigade (Encounter Choice 1)
Move 5 squares with the rider taking an attack in the 1st,3rd and 5th and the Warg taking an attack in the 2nd and 4th.
The Retreat of the Fuzzy Green Brigade (Encounter Choice 2)
Get a quadruple move action, with the first double move free from attacks of opportunity.
I would say to make it elite because I like me my Goblin Warg Riders and don't like to see them die.
