Sounds like clans are going to need 2 versions.
I am assuming you want to stick with your clan or that not participating is not an option for a given war. Have your clans talked about or considered a framing clan and a warring clan?
You can communicate via clan message and even rejoin the warring clan once a war has been initiated.
Would be a tad confusing at first but it would let the hardcore do their thing while the farmers do theirs.
My CW army is the same as my farming army: loonions
And my farming base can be converted into CW base just by swapping out 2 teslas in the core with the th.
So the extra war effort can be minimized, depending on how you farm.
Clan War is not worth the time and Winning Loot, need more Motivation
Me and my Clan have fought in 3 clan wars, going on one more. We lost and won wars, and starting to realized that we can get more and faster loot by just attacking other villages on our own. Then wasting time with another clan war, the winnings are just too low, similar to those goblin battles, which are a wast of our time also. I feel the winning loot should be way way more to be worth the war for 2 days. I won 350k gold/Elixir (yea the DE bug kicked in) in last war, which to me is not much at all. I spent more helping team mates making soldiers. It should of been DBL that +. The losing loot I have no issue with, well we lost it should be crappy.
I hope this in time changes, and in doing so making it much more worth participating in a clan war battles, which is now becoming an issue with clan mates that are now stating this very problem, not worth final outcome and not wanting to spend on troops to attack the waring Base.
As of now if it doesn't change, (which I don't see happening), I don't see me or my clan mates doing much more Clan waring.
