Yeah, it's really annoying to see a feud start in an Extreme Rules match to only end in a normal match. It doesn't make much sense at all. Oh well, until we get promos,(NBA 2K with it's Real Voice thing as an example in having some promo like thing) feuds are just going to be really odd, since feuds like Taker/Punk or Punk/Lesnar never had a match until the upcoming PPV, but they would interact in promos.
I would love to see Real Voice come over to the WWE 2K series, but the promos might have to be generic in getting the guys to speak, unless it's big time feuds, like say Punk/Cena, Orton/Bryan, etc. Those would have specific promos that one would say the others name, but if you want to push Heath Slater to the WWE Title, you might need generic promos, since he's not a popular guy and coding for every possible feud would be insane.
