I know you'll end up killing every boss anyway but am I the only person who most like instances like Ulduar and Icecrown because they felt in some way like actual buildings? Like we had some choice about where we were going, even if we'd end up visiting everywhere eventually?
Mogu-Shan Vaults and Heart of Fear are full of sealed doors you can't open and give the illusion of being big places but end up sending you on a linear path.
I'm not even going to comment on Terrace.
From what I can see of the maps on the front page, the new raid is exactly the same. There are stairs and bends, but only one path through and no options.
I'll still play it and no doubt I'll enjoy it, but I wish they could have used a bit more imagination in their layout!
