Now, in the past, I think I've emphasized the importance of ham in everyone's diet, an example follows:

You and I can both agree that this is indeed delightful, and I was remiss to find out that I couldn't carry any with me because I was so weighed down.
See, WoE:SE and even FE, as well as the new regions far from home, the need to carry many more equips and supplies in WoE, they've made one's pack a thing full of heavy equipment and meatless substances, which I think is wholey inappropriate, really, and then an idea hit me:
Ham passes.
Wait, no, hang on.
...
Gym passes, right. We could use them! A quest, maybe, or a donation thingy! Or something. Maybe a guild purchase? Or a drop from MvPs? I dunno! You decide. But with the increased demand for equipment, as well as things like barricade/guardian stone mats, consumables, and other such delights, I think that Gym Passes are a prudent choice for any discerning adventurer who finds himself lacking ham-like meals in the midst of combat. These are beneficial to all classes and in no way offer a unique advantage to anyone, offer versatility in class builds, and generally help out in other ways. You should put them in. If not for me, for ham. Because ham is delightful.
