The problem with inventory space is that while you get a lot of it compared to other MMORPG, you have even more junk. You basically have to consult an external site just to know if some random crafting material is of any use since you almost certainly won't know that Grenade Ash is used in exactly one Alchemy recipe, for example. Or that there are something like 10 types of fish out of 100+ available that's actually used in something. In light of this you should just have 999 spaces so you can store all the junk that you may never have a use for. Other games have less inventory, but they also have less junk to store.
