Populations still seem healthy and active on Mysidia and Wutai. I actually seen like a group of 6 doing Behest in Drybone the other night while I was crafting. And it wasn't a Ls pt, they all had different banners. So it seems the lower rank camps are picking up as well. Gridania and Ll still seem pretty left out though, as far populace is concerned. I do however notice that on mysidia more people do leves in gridania than on wutai. But that could probably just be mysidia having a bigger player count. More people- more likely to have people in all zones. I don't know.
