class change (we can change nearly everything else anyway)
more character slots (enough that even the most crazy people would hesitate to buy them all)
craft bag (without eso+ requirement)
map and scroll bag for my surveys, maps, etc
bank increase (would prefer in game options as well)
Dapple Grey Palfrey.
I didn't get it when it was available because it was one of the first crown store items and there was no indication any of them were temporary. I got the White Mane first, thinking I'd get this one later, then missed it when it was put on the count down to be removed (if there was a count down? I can't remember now).
Grand Topal Hideaway!
It really does come down to this for me too...
Nothing made me more upset than them announcing it was only going to be part of the Dungeons event at the end of the 2018... I would have gladly threw the ~$100 at them to buy it.
To be honest I think outside of seasonal stuff like the Snow Globe home, all the houses should be in the store, I don't see what the point is of limited timing them - it doesn't really do a good job of pressuring people to buy and it just keeps otherwise welcomed content out of people's hands. (and money out of their pockets)
