A retool of the Shock Troops could be a good idea. Me thinks one thing that they could benefit from would be separating torso from legs for just an extra touch more versatility, and perhaps a little bit of a reworking of the weapons, also (I am one of those who actually like my miniature's weapons to have a resemblance to real weapons... at least in the respect to having identifiable functioning parts, like ejection ports and such).
I might get in trouble, as it seems I've been mentioning this on a few various threads, but I also think it might be a good idea to look toward perhaps making accessory packs for a few certain lines. Yes, we have the Bits Bazaar, and there are a few shops that part out kit (Hoard o' Bits, gotta love 'em when you need bits for a project), but even with those sources there are still parts that are either difficult to find, or that don't exist which would make some certain lines just that much better, or give them that much more flexibility.
I dunno, maybe I'm just wasting wind and I'm the only one who thinks this would be a good idea. If anyone else thinks this might be a good thing then check out my post in the LAUL under "Other Submissions". The actual post is "Accessory Sprue Boxes". Ask questions and I'll explain what I mean more in depth.
