Yes I've always noticed all of those small little improvements that they're always adding. I still really enjoy the look of everything now too, but these improvements can only go so far with the engine they're using right now. Or maybe not, I really don't know for certain.

I do understand, which is why everyone always said there would never be flying in Azeroth, but I would always tell people it was just a matter of time. Although I think that a total overhaul is very unlikely. It's still interesting to imagine what it would look like if it were to happen though ^__^
