Clan castle idea for troops
It's annoying to watch your clan castle troops get lured out by a single archer only to stand there while poisoned to death. The poison spell broke the cc troops for wars in particular where only a Dragon does anything worth while.
I think a way to fix the lure issue would be similar to how the heroes work. Once there are no troops in the given range of the cc, the cc troops will retreat back to the castle and only redeploy when enemies enter the range.
I also think that we should be able to select whether or not the cc troops deploy at all. Sometimes I like to save them for an attack instead of risking them on a defense.
Final clan castle suggestion. I think it would be cool if we could select an effective range of the castle itself. Toggle between standard or close range so they protect less but will be concentrated more.
