Ok I've been reading the forums here and everyone seems to be against combat saying that sub or assassination are the best specs-in my realm I have heard things like "Combat is the only real rogue spec" and "assassination is the worst rogue spec, don't touch it until later for some crit chance." so I'm not sure what it is so what is the best spec for PvE raiding in the opinions of the people here

Realm is Antonidas btw

Whoever told you combat rogues are not the way to go is stupid. I am a combat sword rogue spec'd for PvE. I can out dps any dagger rogue equally geared with myself with no problem. Its really a matter of opinon on which spec suits you best. Experiment for yourself, thats the best way to figure things out.
