I agree in 100%. Removing the war income was one of the biggest mistakes. I can see some purpose in it and the war tax (removing gold from the game?), but i don't really understand why was it needed. Anyway, donating to this game becomes pointless because you can become a farm and grow like hell because no one will ever attack you. Why? No online hours, that was the major change last era and it stopped many battles.
All in all, you will make people quit with this policy. Make polls, care what players and donators think about the changes you want to implement.
War income should be restored.
