It is probably too late for this, but thought I would share my opinion on this from a PvP perspective. I suggest that instead of removing god bubbles and nerfing gods to the ground, that we keep bubbles and have bubbles no longer kill gods, but instead act as the proposed nerf while they are in the bubble. This would allow them to have full power while they are outside the bubble as we know it today.
Basically this update means my days as a solo hunting and goding undermeshes or ninja godding big troublesome clans is over. Gods were the great equalizer. Clans had the ability to defend against gods before, and have done so successfully without a nerf like this. While I think the nerf will promote pvp at the god targets, the proposed changes also feel geared toward larger group warfare and exclude small groups from using gods as effectively. I think my proposed change accomplishes the intent of the changes without sacrifing the little guy.
Just my thoughts.
