I prefer having some varieties of armor go with certain weapons I may have, but it's a hassle to have to click multiple times to reequip everything to prepare yourself for an incoming fire stratum or even PVP.
Say...
You save whatever equipment configuration you have like say.....
Vog Cub Cap
Vog Cub Coat
Skolver Cap [costume]
Skolver Coat [costume]
Cold Iron Vanquisher
Divine Avenger
Argent Peacemaker
Omega Shell
Sword Focus Module
Sword Focus Module
And you save this as your "Vanaduke Slayer" set.
Every time you equip this, it replaces whatever you currently have on with all of the items listed above.
Instead of equipping different items every single time you need to prepare for a different stratum or PVP, you just equip a different configuration you may have.
I think I worded this weirdly.
I think that's a neat idea. I would call them "equipment sets" though.
