We now got restriction that every account can own only one house per server, across all characters. As for this decision alone, I think it is great and how it should have been. However, along with it we should finally get an ability to add our alt characters to friend list, and along that or especially, as housemates. Having just one house on the account is more than fair, if I could actually use that house on the characters on that account.
Edit: instead of letting us friendlist out alts which they seem to be reluctant to do, as conversed later in the thread it would be great if alt characters could automatically have usage rights for the "account house". Such as ability to use vendors, furniture, stables and other house functionality.
