I did WVR/LTW for PUG. Botany definitely helps in the mat-gathering process (harvesting, specifically, not logging).

All WVR mats are easily farmed with your PUG, too.

Moko Grass > Cotton Boll > Diremite Web > Flax > Karakul Fleece.

The only one that's not really DoW/DoM farmable is regular Fleece, which is either made through 40~ Leatherworker or received from high-end Weaver Local Leves.

That being said, doing WVR local leves is a great way to get materials while getting free exp.
