Yeah an ork that can use a heavy bolter sized gun single handed as a pistol is pretty damn impressive in my book.
+ 2 kannondeffguns on his shoulders would be cool ^^ or a gretchin hanging on his back and throws grenades
I understand the size argument, maybe darken the skin color? Or is darkening skin color as orcs grow in power just a fantasy thing?
Not only should devs increase Nobz size, but give them completely new model, that would represent their aggressiveness and battle experience expressed in scars or something. They also have to do this with other factions - new models, animations and so on.
I think this would work as an interim measure before we ask for new models etc. A Nobs skin colour is indeed supposed to be darker than their less experienced counterparts.
I don't know if they've tweaked the animations, but the Orks are seeming quite wee to me right now, even playing as Eldar. With their sort of loping running style, I'm pretty sure you'd get away with having Nobs be maybe 25% bigger (taller at least) without much trouble.
Yes, the darker the skin is, the better the ork is! The most impresive orks where almost black, like Gharkul Backfang.
