The problem is that no one has had a chance to really test out anything in beta, and we only just got access to PvP gear with premades.
And the way it's looking now, we're back to needing Precision, so that's a pretty huge impact on our builds.
Only time will tell, and it's pretty useless to discuss specs when they're still looking at rogues even in the current build.
Be patient, sit down, and read what myself and others post about beta. When we see patch 3.0 come out we can be a bit more positive, but at the moment, everything is still in flux.
