This suggestion would neither fix clan wars/fights at armour nor will make it worse imo. Because there will always be that element that when one gets killed at Armor he/she says it proudly " come 1v1 duel" and when one gets defeated he will call for members and wait at main. Only difference is, now this time there will be more number of players from each side making things difficult than one.
So this will not do anything but increase more of this cancerous comments ("x clan vs y clan 10-0 haha" , "x clan ez"). This will only provoke the other clan and will increase the number of wars.
As much as I like a 2v2 or 5v5, I don't see it going well with ptp community.
