I would like to propose a new 5vs5 only mini war format: 6 hours total for war (2 hours prep, 4 hours of attack) XP is 2 points for each base, 10 for win. This allows 20 total XP per mini war win, so if you win 8 in a row over 48hrs you get 160xp, which is in line with XP of regular war over the same time period.
This would add variety and options for small or less active clans, without unbalancing the whole system.
