Just make ork weapons have more recoil and worse accuracy and much higher firerate with larger mags and tadaa, lore friendly and good gameplay. Or `Ard armor...well, I think I would prefer if it was an actual item that you had to first acquire, either from a dungeon or some other means, and then have the choice of equipping. That way, orks ( and all other races) actually have more options. harder balancing as well, but more variety. And factions are meant to be balanced, not classes, so might work
Ard Armor should would alot like other weaponry or Ork equipment it should be 100% horizontal in terms of changing the ork. An there shouldn't be a "Ard boy" class, there should just be Orks with or without A'rd armor. just like the difference between an Stormboyz and choppa boys, Is that one of them has a jetpack. Keeping things horizontal makes for better balance, than to give (a'rd boys, Mega Nobs, Choppas, Shootas, ect) their own class and attributes that would inevitably lead to near endless tweaking .
I think the playable characters will likely be a bit stronger than just a conventional Ork boy and that would include some extra armor, maybe a cybork body and in the case of mega nobz, the power armor. The perks you select should have pros and cons, with none of them being the all around best. For instance, higher damage resistance at the price of mobility and vice versa. This means more diversity in the composition of each army, otherwise everyone would just use the same stuff.
