That's understandable, especially since these guys really are driven by the hype more than anything right now. Also, I'd argue that the deluxe starscream is a way better figure anyway (best one in the line to date actually), and he's not nearly as hard to get a hold of. Same goes for the WFC Soundwave when compared to the Music Label one, as the mix of retaining the classic look along with its creative touches has really grown on me.
Like, nothing against him or the FE Prime, but I think those deluxes go above & beyond filling the void of their respective lines & characters, and at a much more favorable price + availability to boot.
