This idea seems intersing...and will have to see if the Kingdom's at War developers will ever do it. Henceforth, there are some ideas such as 'Change your build day' That have over 850 supporters and the developers still don't respond to it.
Also you could have a feature added where the vaults money could be used to build battlements that provide stat bonuses to all members in the clan
Support, excluding buying horns and seals it would be abused by large clans. Also an idea in wars an amount of money from vault could be bet
Doesn't seem to help anyone past 500k cs. Hide? What is this WoW? Clan vaults don't work because they are easily exploited with the use of alts.
No support. It changes gameplay too much and makes a gap between large clans and small clans. I like the idea of being able to help small players out a bit more to help them hit the harder EB's, but other than that I don't like it much However it raises a question to me unrelated to this. Wars should be more strategic. There should be some sort of strategic position to hold and defend. A weak edge on both sides that each side tries to take advantage of. Short term gameplay.
No support I used to like the idea of a clan vault/bank but they will be exploited from the very beginning.
