Saying "are they good" doesn't mean anything in beta. Beta exists to test out mechanics, rotations, and design. Number tuning isn't top priority here.
Rotation wise, ret is very similar to WoTLK. CS, Judgement, and Exo (now instant cast, 15s cd, with art of war procs resetting the cd) all generate holy power. Inquisition, TV, and DS consume 3. We're almost back to pushing whichever button lights up and then hitting a finisher at 3+ holy power.
