Now I'm confused. Most of the talk has been about normal modes, which is what you just quoted statistics on. If you want to go for hard modes then you are right that I haven't done them although common sense tells you that simply being able to spread out easier on Al'Akir makes that easier on 10s versus 25s. But if you're talking hard modes then wowprogress would tell us that Al'Akir is indeed easier than Cho'gall.
