I haven't leveled WVR yet and probably never will, but WVR seems harder to level than LTW to me, which I do have at 50. I don't know how much LTW cost me to level, but I don't think it could have been more than 200k. The only items that were hard for me to farm were boar hides, because I picked a time when 4-5 players were also trying to farm them. But, nothing else was really that difficult. I also had MNR at 50, so I never had to worry about alumen. GSM was way easier to level, but I'm glad I spent the time on LTW. Every crafting class I've leveled since then has needed leather, and I'm usually able to HQ some of my AF gear. Plus, Waste Knot II and the LTW AF gear are both awesome.
