You want to sell gear for profit in a guild store? That's not unheard of, but I doubt the margins are high. The only time I ever bought crafted gear was after making a char on another megaserver. It was low level training gear. Hard to get complete sets otherwise. I've never heard Arttea mention this as a gold-making method and she pretty much covers everything on her YouTube channel. Might have been a video I missed.
Off the top of my head Order's Wrath comes to mind as a set people might want these days in both PvP and PvE. You're talking about different weights and traits, though. Light + medium in full Divines makes the most sense I suppose. Total guess, though.
