Nice data! Very interesting. I would just like to point out one thing (and this isn't an attempt to start a cock fight lol). I would say W27 is very active especially considering the number of alliances from W27 in the top 50 during the last xwars. I believe W27 had the most alliances in the top 50 by a fair number.
With that said, no doubt W27 (especially Fin) drops an absurd amount of coin. However, most of this coin (at least in Fin) is spent during xwars. No Fins have finished top 50 in individual global arms races so far. Also, I know most fins rarely coin box events anymore. I believe we only have 1 maybe 2 members that currently do box events consistently. Just something I thought worth mentioning for future data.
Also I will agree that Fin does dominate W27 (not trash talking for those of you in 27, just a polite discussion) but so do most top alliances in their respective worlds. With that said, I do believe that the rest of W27 is very competitive. There are always close battles for 2nd and 3rd as well as the other positions. Fin members (at least the original ones) tend to leave lower alliances and lower level players alone (assuming they dont purposely piss us off). I personally believe I always try to help players in my world when they ask (idk maybe someone else from 27 can chime in here). I think it would be good to look at alliance war bp totals for world activity. The last alliance war in W27, Fin accumulated over 3B bp while alliances 2nd through 4th all accumulated well over 1B each. Thats well over 6B UV in the top 4 scores alone. People may argue that people boost in bp events but I can assure you Fin is not boosting in alliance bp events and considering the fact we are winning by 1-2B bp, I think that is pretty believable since there would be no need for boosting to win. Anyways, my point is, all that UV had to come from somewhere which is why I believe W27 is still fairly active and competitive.
Maybe someone else from W27 can weigh in on this. I obviously have a skewed point of view but I would say I honestly try and look at things from all points of view.
Also, I'd like to reiterate that I am not trying to start the "my world is more active/better/this/that/etc. debate". I agree with a lot of the statements above, just trying to have a friendly convo
