Are total captures up or down? Are total kills? Hours played? Total damage points? GV captures and kills?
absolute total captures is not a very telling number as it also depends a lot on total player numbers, tour length and other factors.

New towns - Tour 126
Offpeak system - Tour 131
Town requirement set to 50% and white flag - Tour 131
Town requirement 75% - Tour 132
Back to single MA - Tour 137
Change in arena setup (split LW MA vs offpeak system or single MA) had a big influence because they made sneaking bases in a low population arena more difficult.
Also you have to put the raw numbers of captured bases and the ratio captures/time into the war perspective: There are much less bases needed for reset nowadays (about 5 from each country on small maps only!). This week we had at one time two map resets wars within 24 hours.
My opinion on thee OP wish: No, thank you, I think it's fine now.
