It's very potent, and that will help you become comfortable with the spec prior to heroics, since you will be Survival through questing and normal dungeons. This is important since Survival is, by far, our highest DPS spec right now.
Also, don't forget to browse through the 4.0.3 guides stickied on this forum, as they provide very useful information to help you get caught up.
