If they don't actually improve it (whether initially or eventually), I'm going to say that a bad translation is actually worse than nothing, personally. I'd rather there be a chance of a good translation than being stuck with a bad one. Especially because it really does look like they're translating it secondhand from the Korean version. (And, also, the JP and Korean iOS versions only came out in December, so...)
I guess another company could hopefully still release the Vita version...
EDIT:
oh lol they really did just reply to every single post individually, huh; I'm guessing a TA mod is gonna warn them
