With new game play modes and GvG etc coming in, I hope devs shorten GW. The most time consuming and repetitive game mode for me even now, I dunno how I'll cope with it when all those new modes pop up....
Please don't. GW is my favourite part of the game. I can't wait to do it everyday. I wish it was harder and longer. It's the only game mode in the game that we get to play regularly. Why do you even play the game if you don't want to play the game?
