No there wont, sometimes I wonder why I am reading the forums here at all. So much whine when people dont get exactly what they expected its insane.
As for sentinel or guardian being op they both got some nice pros and cons, using your survivability cds on the right time against each other is the key. Dps wise they are very close if they are on the dps tree, but then guardian loses much survivability as compared to tanking spec.
The only time guardians might be a fair bit stronger is when they are playing with a pocket healer compared to sentinels with one. That doesnt happen often though. Also once you have one tank/healer team the obvious addition to such a team is one dps.
