I am sure that if DOA started to get some more popularity more players would invest more time into it. Yes, many players play to get better themselves, however... If someone wants to play fighting games for a living because they love it so much, they should be able to! However, they would be stupid to play a fighting game that they couldn't make money at, right? If their objective is to be a professional fighting game player, then they have to play what is considered a "top tier game". They might play DOA in their off time because they love it, but when it comes time for "work" they have to play the game that they will be playing at EVO or any other big tourney they go to. If DOA becomes popular enough to consider for the player to invest time in so they can make a living playing it, GREAT! But, its not there, and for a pro player to not play what is current and relevant would be foolish.
