donno how popular it would be, but id think the only maps that would work well on rotation, are same type maps, such as our arena maps, so a rotation of,
Hydro
Well
Granary
these are CP maps, which I think would work best on a rotation serve, beacuse they give an equal oppertuinty kinda thing, not one side defends the whole time, then the map changes, but that can also change depending on how much time is put for each map. But I still think a CP with maybe even some CTF maps would work best in a rotation. And theres less chance of one side being steam rolled over and over again with the teams switching up, but that can be said about any rotation server.
