That's why they're releasing all these new teams with absurd power creep. Because "new shiny!" makes them more money than GLs do. They do make a bit from GLs granted, but those are once a year as opposed to releasing 10 marquees in one year and the money they'll make from that. Especially if they tie those marquees to GLs and/or epic event / legendary characters.
Dont' worry though, just relic your whole roster to R9 and spend 10,000 a month on datacrons and you should be fine, as CG expects us to do.
I've been saying for a few months now that all these new characters are adding too many offensive weapons and GL's aren't "The highest tier characters in the game!" anymore, though CG says they are. (Not the first time they've abandoned a power model.)
