There are 3 addons that do that: Alpha Gear, Wizards Wardrobe & Dressing Room, but which one is best for me? Until recently I thought you needed an armor slot to swap gear at your armory station. Changing your CP costs money and these addons do it for free? I wasn't getting it. If I understand correctly AG doesn't change cp and the rest do. So, you can save a state with gear, skills, ability, ww/vamp states, mounts, polymorphs, etc. all of that in a specific addon slot? And then do a total work over and do it again. You can now swap between these 2 slots in or out of combat? You could for example change from a magicka cloth wearing vampire to a stamina medium armor wearing ww without cost? And some swaps occur automatically when for example you enter a dungeon?
Now, I don't even have 2 sets of gear and not all toons have master gear. At most I use the ring of the wild hunt and ring of the pale order. I don't want a complicated addon. I also use an addon to see if I wear the pale order ring and I take in off manually in dungeons.
