This what i've felt too.
I've been in dmm aigis discussions or in chat rooms for some time, never heard one guy complaining about something, they always discuss about in-game stuff, debate over them, not any chat about dev or promises or something like that. Ofc he is right to not to give a damn, i would do the same because you're comfortable with where you at after all. I can easily say, especially after damn S-Legend stamp card shit and many players started playing dmm after seeing failures of nutaku (we cant be certain if its nutakus failure or not, but people see it that way already) i guess dmm found the potential money on our community and wants to control it instead giving it away to some publisher despite how they will bother themselves providing us same old style content...
