Ok, so I'm a Combat Rogue. I use daggers, but I don't really like to use Backstab often. I'm not 70 yet, but this is the build I'm thinking about ending up with. I'm sort of a nub on talents, and don't really understand why people wouldn't go with Blade Twisting, to be honest. It seems something decent to use in PvP.
I'm not much of a Slice and Dice user, but if it's recommended, then why not? :| I don't use Kick much, as it's not really my kind of thing, and I don't use Sprint as I already have a mount, and impairing effects aren't that much of a problem to me.
I used to be a sword lover, but after finding a really sweet dagger from Naxx, I decided to change. And using a dagger and sword was awkward for me, I went with the dagger I found in Naxx and any dagger I can find from a quest reward or something.
This is my build though. IMO, Murder doesn't look much and would probably not make much of a difference IMO. Please, don't flame or critcize x.x I'm not very good on talents, and I choose whatever I think is good. Constructive criticism pl0x.
