It was announced recently that non-combat pets and mounts would take up no bag space in Wrath, and instead, the item that currently houses the pet will serve to teach you a spell for summoning the pet, and then disappear.
While this is a huge weight off of the shoulders of many players, when reading through the current list of Achievements, one begins to wonder where all of their tabards, battleground tokens, badges, holiday items, epics, trinkets, and the like are going to go.
Although we don't have information regarding the storage of every item we'll soon be collecting, Tigole made the following statement:
Your bags will be ok. I promise. Pets, Mounts, Heroic Badges, BG Tokens are all getting storage space.
I wonder how badges and tokens are getting storage space. Surely, they cannot be turned into spells, and I don't have room for bags specifically dedicated to only one or the other, so I'm definitely interested to know what they have up their sleeves, and if any other collectible items will get similar treatment.
