I'm sure an Ambulance match ended the Elimination Chamber feud this year so you should just be happy you got that.
As for No Way Out jumping to behind SummerSlam just makes me think they are trying pretty hard to put over SummerSlam this year. It used to be before Mania and now it's before the second largest PPV while Mania has a clusterfuck from the Rumble, to the Chamber, to Mania think about. So I guess maybe we could get some more traditional booking like Mania used to get. This alongside them adding everyone's favorite Money In The Bank to SS, WWE looks like they are beefing it up.
