Why, Why, Why?

I am just wondering why Konami decides to make some Archetypes more playable than others.  There are so many interesting Archetypes out there: Koa'ki Meiru, Psychics, Dark Scorpions, etc, but Konami just gives them half ass support or totally forgets about them.  In Extreme Victory, apparently Psychics are getting new support involving the RFG mechanic, but if they don't include ways to quickly fuel that mechanic specifically for that Archetype, it will again be another half assed piece of support.  Let me know what you think.
