Instead of that random backpack, I wonder why they didn't include the spore pod that turned him into this monster...
My best guess? They can reuse that backpack mold and the pistol for another figure. A spore pod not so much. I agree, your version of it would be really cool.
Unfortunately each part they make, even the body parts, will be evaluated long term for it's potential reuse. For example, that core Stalker V1 body mold was used a lot. It's why I'm a little saddened that someone like Sci-Fi might take a while to get to us. ( I mean how much of that guy can be reused? ) But someone like a Muskrat, could you probably get 75 percent of the way there with preexisting molds/parts.
So figures without reuse options, those are possibly the candidates to get shuffled over to Tiger Force or Night Force, etc. There's a lot on Tripwire that can't really translate elsewhere. Hence now he's also Tiger Force too. I recognize there are original RAH roots to some of this too, but it's why I'm not so concerned about figures disappearing forever ( They can't just make one rare Major Bludd and never go back to him again, that makes no sense at all)
I'm going to say something unpopular now. Just raise the price point. I'd rather see 29.99 Classified as mainline standard with a larger and more complex suite of accessories and fewer corners cut. Better QC, better paint, more weapons, more chances for creative add ins, etc, etc.
