I personally enjoy it. I'm always checking out the new packs and deciding how many of what I will want and need. That said, I haven't unlocked all of Core or DM yet, but I have a fully unlocked and decently (60%) decorated Tatt. I plan on unlocked most of Y4, but I don't think i'll decorate too much of it.
I like the option, i like that it's not required (like the new blizzard games crap), and I like that we really can make it seem kinda homey.
