Good suggestion, and on that note, I'd also love to see a sort feature where it auto-sorted the armory gear by level, however with the option to separate gear by discipline. So it would be a row of duty of war gear, then magic, then hand, then land, all sorted by level. This would make it easier to find gear upgrades as your levelling your second/third class etc.

One alternative (although it would also be good with the current, or suggested system) is to show the item equip level on the gear icon, without having to mouseover it. Once again, this would make it much easier to find the peice of gear you want to equip. It would look exactly like it does in your signature Jonno, with the numbers on the icons of the gear.
