You would keep Layla as Divas champion after still no reaction from the crowd?
Yes, but I would actually start to build up to the match like a month or more before WM to get people into it. WWE are showing they don't care about the divas and the tag team titles right now so the fans aren't caring about them either.
Taker vs Kane happened too many times and last rivalry proved to be one of the best they ever had.Can't top that!!
HHH vs Taker happened 3 times at WrestleManias so I think Kane vs Undertaker will work. Plus I'm a Kane mark I can watch them wrestle every ppv.
No Lesnar at Wrestlemania? 5 million for 30 dates and you don't book him for the biggest show of the year?
I don't really like Lesnar and wouldn't miss him but you could throw him in the WWE title match and make it a 4-way elimination match if it makes you feel better.
