Food and drinks!

Tabards.

I have 178 slots in my main's bank. Of those, only 38 are empty.
I have about 10 with different cooking mats. The rest is full of useless items from events, funny quests or stuff like that. I don't know what I'm going to do with all that space if I can send the gear somewhere else :P
We'll have to wait and see.

Puppies. Definitely puppies.

I've seen this in the other posts later on down the line, but I feel I need to mention it; the cosmetic changes will probably only extend to armor, not weapons. The simple fact is that I could walk up with two level 1 grey axes and another player wouldn't know that I actually wield 2 353+ weapons instead. That will probably be a bridge too far for Blizzard. And frankly, they're right. So you can modify your armor appearance in all likelihood, but not your weapons.

Pets, Mounts, and Keys.

Oh wait...

So? If you are masking your armor what difference does it make then if you mask your weapon? I am going to assume you can only make your items look like certain ones they have pre-loaded in so I doubt they are going to load in a lvl 1 grey item. We shall see. Either way if you are masking your armor- masking your weapon would make no tactical advantage. I always go by health pool. The health pool doesn't lie.

I'm going to use mine for stacks of what is arguably the best item in the game-- Lunar Festival Dumplings.

Also, my rock collection.
