Have a completely separate army camp for war so u dont have to worry if urs is full.
This mite be difficult to program into the game but it would b nice if u had a separate army camp for wars. I always make troops after each attack so theyre ready faster. But sumtimes wen a war starts i have an entire army for farming. U cant always just attack or drop all ur troops to make room for ur war army. It would b nice to have a war army camp so it will always b ready for ur attack. U could even transfer troops from ur regular army camps if u want.
