Its just a push so more people can play the DLC Raid when it launches. I've done the raid multiple times and never gotten 1 single raid gear or raid weapon. On my most recent run, I played with a guy who had never done it, and he got 1 piece of raid gear. It's more luck than earning. I grinded in the raid AND in the IB, and the IB was a definite reward. I'm tired of RNG -blam!-ing with people. So I earned my level 30 gear just as much as you did.
