The only thing I can say is I really, really wish Blizzard had said they were NOT breaking addons, but were instead just baking them in, leaving the addons capable of still being used for those that prefer them.
We all have our opinions on this change. Personally, as long as they dont touch the customization addons, im fine with it. (Of course you are Meri, look youve only timed 5s lol scrub).
But they really, really need to remember that more options is never a bad thing.
