If you set the option to using the equipment manager, those saved equipment set buttons can be dragged to your button bar, allowing you to instantly change your equipped gear (while out of combat) with a press of a button.

Since weapons can be swapped while IN combat, it also provides for the ability to have multiple weapon configurations if you like to have different weapon sets or sword and board or weapons with weapon chains JUST for fights against foes that disarm, etc.

But nobody says you can’t use it for fun sets. my Rogue has a “DPS” button and a “town” button, to proudly display her full set of dungeon level 2 rogue loot. Now my worgen has a DPS button and an “Imp” button on the bar. The DPS button has to be resaved every time I change/upgrade my gear, but hey… it’s no problem.

Even better, if you mouse over a button for a set on your bar, it displays all the gear in the set, and any pieces you may not have in your bags show as red, so you can see which ones are out of whack.

Your worgen looks good though. I might have to try it out from step one though… Im not rich enough to do faction changes :D

…too much “town”?

*ahem*

Yeah, those are some great screenshots. :)
