A very simple idea, make one of the ESO+ benefits a furnishing bag, which would work basically like the craft bag, but for furnishings
Why? simple.. some of us are sick and tired of having to clog our banks and inventory [for me personally it's getting to the point where I'm considering going "*** it" and throwing all the furnishings out and giving up on housing all together]
"Why not just use a house as furnishing storage" it's a pain in the ass to do that, plus not everybody in the situation can actually afford more than one house...ontop of that it makes it a nightmare to actually..use the furnishings as it were
Plus, taking the hassle and annoyance out of the whole furnishing storage issue would...well, make furnishings more attractive ans an item option [which known zos means they would sell even more furnishing packs]
