Is there any particular reason you can’t equip all your Home Comforts at once?
I think I’ve collected most of them at this point (except for a few that are inferior to those I already have) and I just can’t see it be that unbalancing. It’d be a noticeable bump in BDR (3-4 points, I think) for those who got all the Incarnadine Robe gifts, so I could see disallowing those from being equipped together, but having the tiny stat boosts from each of the other home comforts would make them sought after collectibles, especially for capped players, instead of "yet another item with no card, that I can’t sell, that is worse than something else in slot." It would also make Midnighter a better profession, but that’s not critical.
I’m also not really clear on why you can only have one at a time from a lore perspective. I could see maybe limiting it based on your lodging (although I imagine that would be a technical headache to implement.) but having room for only one "thing" in your house doesn’t make much sense.
This is not meant to sound like a complaint, I love my items even if they’re not useful, and I don’t regret any of them. I’m just representing a side in the argument in the hope of hearing other points of view.
