Are you forgetting that Creators need to spend tokens on woe supplies too? Creators do need to stock on yggs and FCP tickets as well. FCP for the obvious reasons and yggs not only for HP but also SP from skill spam.
I constantly need to spend about 100m in zeny to "reload" my creators bottles and that's not just during woe but in any situation there is PVP. It's really quite draining. I've definitely sold a few tokens for zeny.
Changing the price of the bottles REALLY is not going to change the fact that AD can be quickly spammed and create a great stun lock so I don't know why that is even being debated...
Usually classes with ammo are expensive but it seems as though if you play a GS, Sniper, Gypsy/Clown, or even Ninja you don't need to worry about that cost but when it comes to creator, all of a sudden it's about restocking and buying more supplies.
