I have thought for a while have 2 or 3 different settings for war but keep them basic.

1st: make a war where prep is half a day and war is half a day for players that are more hardcore. maybe bump attacks down to just 1? that last part just thought of don't think it would work.
2nd: keep the normal war that is in the game now
3rd: have like a 3 day long war for more laid back clans that are not as active


just some thoughts and that idea might already be out there

clash on,
Michael
