Is Transmogrification linked to the slot, or the piece of gear?
For instance, if I transmogrify my heirloom helm to look like tier 1 helm, then at 85, I get a 346 helm and switch, will it look like my tier 1 helm or will it look like the new 346 until I re-transmogrify the new item? (AKA Are you binding the look to the equipment slot, or the specific piece of gear you currently have in that slot). And secondly.
If you have 1 One-Hand weapons, can you use that single weapon as a model for both of your dual wield weapons? Or do you need 2 of the "One-Hand" weapons in order to put it on both of your weapons. (Not referring to main hand or offhand only weapons, specifically one hand ones)
