Small quick suggestion.

I don't recall anyone else suggesting this. Quick and to the point, I don't think vanity items should take up inventory slots.
Reasoning why:
Like many events, particularly the Easter event, ears take up MANY slots. 13 to complete the quest, and the 14th reward, not to mention full bunny ears. 14+3 special ears, is 17 slots taken out of your inventory for raiding.
Just store them in the stash? Well, that's a conclusion, but when you have more than one toon that you use, that not only cludders your stash, but depending on how many toons you have vanity items on, that's again, is a VERY large portion out of your inventory gone.

Conclusion: Make vanity items not take up inventory slots.

Anyone else's thoughts? :]
