After reading and doing a search on the PP forums, the battle boxes are still considered balanced toward each other.
So, if you get to play your pirates because that is what YOU want to play, why can't I play a Karchev the Terrible beat face list packed with heavy 'jacks and character jacks? Since, you know, that is what I want to play... (not really playing this, I am going in with menoth...just pointing out the fairness, or lack thereof, of letting one person play what they want to play and not letting others play what they want to play)
And by saying "just ban the broken stuff" is a bit too "Austining it the F Up!" We don't like it so ban it! Warmahordes doesn't really work that way. Nothing is Purple Sun broken in the game, everything eventually balances out the higher point value you go. Things can just get alittle unbalanced at under 15 points and that is why we have battleboxes.
