Please do not make these restrictions similar to those found in the dye system. Restrictions like this would make the proposed vanity system completely useless, much like the dye system is now for DoW or DoM (you will never be in dye-able equipment when wearing best in slot for any DoW/M). Since we will be changing the look of a piece of equipment it would be nice to have the option to revert as well. But most importantly such a change should not consume items or equipment in a pay to play model. Vanity options in a Pay2Play environment are quality of life enhancements meant for player enjoyment, punishing the player with barriers of entry and inane restrictions/costs is not acceptable and should be relegated to free to play. Such restrictions are popular in F2P because they are monetized and you can "pay to win" by immediately bypassing said barriers or restrictions with a few dollars, or a hefty amount of in game currency from other players.
