Does anyone use grots/gretchin in their Ork mobz? Are they just taking up space on vehicles, better off spending points and space on a yoof instead? I feel like they might have been a bit more useful with an extra point of initiative? kind of makes sense that they'd be a bit faster than orks? I have read on various parts of the interwebs that they are good for picking up scrap but I don't see anything in the rules to suggest that. Is it more of a fluff thing in that that are only good for "fetchin"? On a side note does anyone use Diggas in their Ork mobz? Digga Shaman with his 2D6 "scrap dance" seems tempting.
