What they should be doing is working to have more balance with "Defense" being strong. Bane is just another offensive weapon, among too many, while defense is becoming more and more useless. K1 is turning into a "half the battle" tier where people put down rubbish, a couple banner stealing teams, maybe 2 GLs, then save everything else for offense to do a full sweep.
While CG said that GLs are the top tier (best of the best of the best Sir, with honors!), CG will continue to power creep them with other characters as the other characters make them a lot of money.
Of course, Ahsoka will probably be what all GLs should be, but we'll most likely need Fulcrum at R9 along with snips and CAT and they'll make her even more expensive.
Don't count on anything other than more "new shiny!" characters and teams beating anything and everything. With or without datacrons. (Don't forget to just R9 your entire roster!)
