I'm getting a lot of XP just from grinding out materials I need for my Weaver that I'm leveling alongside the Botanist. After that I'm just trying to do everything in the gathering logs for that XP. That takes me most of the way to the next class quest and gathering log/weaver level range, but if need be I can always grind out random gathers. But having a purpose to what you're doing, along with breaking it up between Weaver and Botanist, makes it more fun for me. Just mindlessly grinding is going to get boring, but my methods now feel calm, fun, and purposeful and the mini goals I set for myself along the way keep me going.
