Can you make the Dooms Gate more powerful so it will be interesting to fight for in war? Many alliances find the Dooms Gate no reward to fight for.
An idea would be intimidate bombs like the Heavenly Haven, Electric bolts to freeze enemy troops for an instant or an ability of a tower that is placed at the gate. So for example, poison will be thrown at enemy troops when a Snake Tower is placed at the gate.
Anyway, please have a look at the Dooms Gate.
