I don't so much think it's a case of haters/miniscule love for the character as much as it's an acceptance that Hasbro really don't want to fill this gap - and that a Universe/Classics Arcee is a more attainable goal.
She's not _that_ momentous a character, so Hasbro don't see Arcee as a sure thing - and at the MP scale she'd have to be.
