When I initially watched DNC videos after the media tour I thought: "Cool, surely the dance moves will be on Cascade, Fountain, Windmill and Bladeshower. Then I can have the single-target and aoe combos on my 1-2-3-4 since obviously those buttons will change into their enhanced counterparts when they proc, right?" Well imagine my surprise when I get my hands on it and they're all separate buttons. The only reason I can see for that is so they can have 8 buttons instead of 4.
