I don't think this (the topic) needs to be done, but I do wish my character could be more than one class.
No human being can even be close to perfection, not after 10 years not after 20 years, basically never. If anything, it will get incredibly boring during that time. So yeah they should continue to revamp specs. Like they did with demo lock, which I consider the best spec ever created. Nothing comes even remotely close.
