In the new build 1.18.1, XMP burster range has been heavily reduced. I had already upgraded to it, before finding this out and reading suggestions to stick with the previous version.
I expect that the calculations are done server side, and keeping the previous version would just give animation of a large radius explosion, but no real benefit. Assuming this is true, there would be no advantage in downloading an older apk and downgrading.
However, I haven't done tests or read about any definitive information on this. Hence, my question: is the range determined on the client, and an older version would actually make a difference?
