Some in my guilds would like a global ranking of the guilds based on points. I think it is a bit irrelevant as we’re all facing different guilds in different brackets.
But what you could do would be to setup 5/10 fights (the same for every guild) then we could get a ranking on how well did the different guilds do as we would have a score based on how we fought just for these fights.
The frequency could be up to you (we know you’re busy adjusting Famine’s spell 
) but that would a fun addition to the GW. Especially as you could put in any sort of conditions to get a better score: start with only 3 troops, common based troops, etc…
