I played IB 3.0 with my friend for the last 2 1/2 days trying to hit rank 5. We did it. I bought the auto rifle (can't wait to use it) and the emblem I didn't own. Later I will get on, grind glimmer, and purchase the shader I don't own along with the sniper rifle. Then I will grind even more glimmer and purchase boots an gauntlets(this is a maybe though. I already have good armor.) Drop wise, I got two legendary ships and Perun's Fire. I think this was a good IB. I have my new crucible gun, a new fusion rifle to play with, and some nice shaders / emblems. Did you guys get rank 5/ enjoy IB?
