I dont know how this really helps the community.
I am particularly concerned about Legendary Champions. Its been almost three months and no update patches, bug fix patches, very minimal communication.
Although GMShirnky has been a lot more active but still. Having an active GM doesn't cut it anymore. Not when we are going on three months without any updates. People are leaving left and right because almost all the active players are at the level cap and have nothing to do anymore. Half the game is till broken.
If this "GM Crossover" means that we will get updates and the game will become active again, I'll be extremely happy. Otherwise, its really means nothing. Sorry.
