It is a bit difficult to keep track of 400+ potions in your inventory, since that means that you are losing 40 inventory slots, with no alternative. I suggest that potions should be able to be stacked in sacks, or to have some ability to stack them together. As a warrior, I'm very dependent on my potions for buffs and for heals, and I'm sure pretty much every other class is too. Also, it is nearly impossible to make many potions and then stash them away, because you can easily fill up your bank by doing this, so I think it would be a big favor to everyone if we didn't have to destroy our inventories and banks just to stay alive.
Thanks, and please tell me what you think. :-)
