I think releasing more expensive powers consistently will just continue to alienate more users invested in powers.
I think the site needs a higher population before anything with powers happens. Letting people make a little bit more profit just comes off as a short term solution to make people a little more happy but maybe that is what the site needs who knows.
I think there's so many powers now that raising the price won't even matter. I don't think there is any reason to believe that more expensive powers will retain the same percentage increase that new powers show upon release.
When old users I have known visit xat and we talk about powers it's not really the 100k tag behind ruby that we find funny or are frustrated about but rather the fact that ruby was stripped from the old everypower and then given the 100k tag.
The admins didn't catch enough heat for this move probably because there wasn't enough people on the site.
