I think it would be a good idea to get new maps for Decor Duel themed with other factions so we could get more house decor not tied to current narrative/expansion theme (well, mostly elven style). Lore behind it: Blood elf spellbreakers teach Nightborne, High elves, Void Elves (and maybe Night elf arcane mages/demon hunters) some of their skills.
For example:
Map 1 - part of Silvermoon as it is now (there is still a lot of items unavaible for housing like nightborne themed arcane fountain more in blood elf style, scrolls, books, middle size elven bookcase, braziers, iron bars etc)
Map 2- Part of Suramar city, maybe gardens near Magistrix estate with Nighborne decor rewards
Map 3 - Windrunner spire/High elf town nearby themed with High elf items (mostly blue versions of Silvermoon items I think)
Map 4 - Voidstorm/ Telogrus rift themed with void elf/cosmic items
Map 5 - Bel’ameth themed with Night elf/druidic/nature items
Map 6 - Fel Hammer/Mardum themed with legion/demon hunter items
What do you think?
