I'm sorry, I don't like the custom UI. It's painfully crowded, bordering on claustrophobic and it offers nothing functionality wise that the current one doesn't already have. Yes, named games and characters along the bottom of the screen are neat and borderline mandatory because, hey, *D2 had them*, but it's hardly a game changer, and I honestly haven't missed them.
The soulbound loot sounds like a pretty good way to combat restoration fraud. I'd like to see it in the US as well. Those screens OneTwo posted were pretty nice looking as well. I don't dislike the way things are now, but seeing a better iteration of matchmaking and the lobby would be nice.
Out of all the options, the Crystal Arch was the only one I felt comfortable with voting for. I like the pretty areas, but they are wholly out of place with the theme of Diablo. It's also shorter, which doesn't help.
Abusing account restoration is a sh**y thing to do. I had my account restored 7 months ago for WoW and parts of my account are still restricted. I've been mostly angry at blizzard for this but I'm sure it's fraud like this that makes this process a nightmare for legitimate players. I still wish Blizzard would help me already but I guess it's their loss, I just stopped playing. I try to restore every time they give me a promotion but all they ever do is refer me to other departments.
I think we should be allowed to customize our Interface more, or even open a competition to see some really cool ui's that people could create. Can't wait for Heart of the Swarm, let alone sc2; part 3(protoss) !
