I'd say more fighters in general could use more attention. Lack of cross-play hurts them immensely, and a percieved notion of "I can't play fighters, they're too hard" is just another sign showing that most people don't want to put the effort into learning basic functions of a game; they'd rather have an immediate "know-how" followed by a struggle to perform better.
It's really a shame, since the effort some people put into some shooters or RTS games could prove very effective in fighters, and at least on PC the highest playcount for any fighter wavers at just a few thousand, whereas many popular shooters have tens to hundreds of thousands consistently.
