Really iffy on a one frame only cosmetic like a helmet being primed. Every other time it's been an armor set, a syandana, sometimes a sigil. these are great because any frame can use them. But an alternate prime helmet? I won't deny that it's cool but..... i'll never be able to use it with anybody but Mesa prime. I've always thought it would be kinda neat if prime helmets were a thing, and universal helmets would be cool too. if this were both of these things that'd be awesome and i'd no doubt work my best asset off to shell out for it. But just for Mesa? Eh. I'll buy cosmetics even for frames i don't normally use because they look great and they don't cost too much. but $50 for one? Can't say i would be able to justify it on my usual budget.
