I think part of that has to do with the nature of orks. They aren't portrayed as being perfect in every way. They aren't uniform. They don't win every fight they get into. They don't hold off 1000 space marines with a single knife. The whole "oh the elder are to tall!" "Oh they have shiny stuff on them boo!" or "Oh Space Marines need to be the best!" just doesn't effect the Ork playerbase. We just want...fun.
Da jumpin' lookz a bit odd, Iz neva jumped 'round when punchin' a git in da teef, but Iz like da motionz. Da powa klaw lookz zoggin orky, Digganob likez it. 'eard 'bout da chain axe too. Gunna be 'ard fer me ta pick from da two, if we boyz get ta pick it.
I think the Chain Axe is actually a Chaos Space Oi Shootah! Youz alive! We haven't seen ya in da alpha yet, why don't ye' send an message to me and we'll get you setup on da Clans team speak and Steam Group!
Hmmmm good point we need more threads discussing the overly sexualized nature of the shown orks. We will just be too sexy and distracting for other factions to focus enough to play.
