The game needs a way to create and mark item sets for players to allow quick gear swaps. I got luck gear, PVP gear, PVE gear, crafting gear, farming gear, etc… All of them require me to mouse over my inventory to find the gear sets and put on each individual piece.
If it was easier to switch gear I might flag for PVP more, but when I am out in the wild I am usually running luck gear or farming gear and my stats are way too mismanaged to fight someone.
