These all sound like good things. Now one guild can't easily hold every city, and guilds must plan out strategy carefully for defense and offense. To me this sounds a lot better than defense saying "Okay all go B and turn 1 kill A" which was what was happening in 90% of GWs before we decided to overhaul it.
Your overhaul sucks!!! There is no way someone with 50 mill less power should be able to take out 3 others who should crush her in one fight like what I see happening every night; people quittin this game left and right these days and I'm next.
