With the pre-patch changes coming soon, I'm wondering what people's opinions are on the revamps that will be coming out (even though they might be "incomplete" gameplay-wise until you finally get your artifact).
For me, I'm most looking forward to Death Knights, I think; each spec seems to capture a "class fantasy" really well and looks like they'll have many fun and hopefully visually impressive abilities to use. Of course, it'll be impossible to completely form an opinion until I get to play each class and spec, but the order in which I'll try them will definitely be "seemingly most interesting" first.
