I know PvP isn't all about dps, but honestly I don't really see the point in having any other spec for rogue except combat right now. Blizzard seems to have given combat some HGH. I've seen numbers from various geared, leveled, and experienced rogues for all three specs and combat seems to always come out on top in numbers.
But, like I said just a moment ago, PvP's not all about dps numbers. You have to play, live, move, and dps all at once. I get that. I guess, in my own personal opinion, you're going to die in PvP anyway so why not try and wreck someone as fast as possible before you die? Go combat and bring the pain. Why? Because, as it stands right now (and keep in mind this is only from what I've used so far) the combat CCs that are listed are just crazy good compared to sub/muta rogue CCs (CC devs that have made sub/muta CCs I swear I mean no offense. I don't own those types of rogues, so I haven't tested the CCs recently since some of the changes to class have come around). Just stick with what works, earn your honor, spend it, and then do everything else.
Sorry, not trying to sound douchey or anything. I was just trying to make sense out of all the requesting for sub/muta rocue CCs when there are perfectly good combat ones laying around that outshine the other specs.
