Well im a huge WWE fan.
Id have to say my favorite is CM Punk then Rey Mysterio. I hate sheamus, randy orton, R truth and Kevin Nash(even though Nash is super fun to watch)
I also like Daniel Bryon and The Undertaker.
My favorite feud ever is the one between CM Punk and the Undertaker, Then CM Punk and Triple H.
Im not a fan of the RKO and Cody Rhodes feud (i prefer Rhodes in it though) it just isnt that entertaining and doesnt have much build up.
