Lol at all the people who are saying this is a giant timesink. Nothing has been changed in the manner of collecting gear for your character other than convenience of not having to take up an item slot. Now people misunderstand something and immediately freak out. It's pretty hilarious when you really think about it. If people really cared that much about xmog on all their characters, they've already spent countless hours grinding out that gear, possibly still doing it. Now people want to be like, "I got this awesome cloth helm on my hunter, Blizzard HAS to let me put it in my wardrobe on the off chance I play a priest/Mage/lock in the future!"
This literally changes nothing (except a QoL increase from more bag space), adds no new time sinks, and doesn't complicate things in any way.
