Like, furniture and decoration stuff- don't get me wrong, it's nice! Again, I tend to like the decorating in this game (although, i'll admit, it's been ages since I properly have...) but... You can't always show those off to people. You can invite people to your plot, sure. And it's nice
it's something, and i'll admit that. but you're not always going to be on your plot. Having something for your actual character, while you're out grinding for those materials that you'll need... it just is enjoyable. Or hanging out doing hotpot, having a title or something that showcases stuff.
It'd also give more community-aspects-- I know people already try to do some "fashion shows" and i think it was something way back at the start of open beta? but I don't see it too often now, because it's not the easiest to do right now, since ... well, you'd have to buy a lot of the cosmetics. It'd be more of a "community event" that people do, or experience, if there was more F2P options, esp ones you can grind for and earn imo.
