It's goofy. My buddy jumped in my Sepiks Prime fight and got a legendary within 30 seconds. He got another on the next fight. I have yet to get a single purple drop... It's not all that bad. I received a couple of purples from reputation bonus packages and blue engrams that upgraded to purples. Also received my second exotic bounty. It some how levels out. Only over the top thing was the lowest level guy in our raid party being the only one to get any actual class items. He got 3 legendary items (arms, mark, and sniper). I got all shards and a machine gun at the very end. Really unpredictable but I guess that's the allure. I used a boat load of my energies and shards to upgrade so it's all good. Can't wait for the next time going in.
