Who would have thought that first mover advantage would be so big in the FGC space 
they did almost everything wrong you can do a spinoff product:
the marketing.
the name.
the business model.
the subgenre.
a full price 1v1 focused game with branding that clearly connected it to league and with a fat roster (idk make a lot of characters about the same with different specials unique supers to save money) would've been way more appealing to their audience.
instead they make some tag nightmare when they said they wanted it to be approachable to new players, and did fuckall to reach the sickos who like watching league or to have enough characters that enough people could play their main.
