The original 3oC worked VERY differently. You popped one and then fought a yellow bar major enemy. If an exotic did not drop, then your chances increased the next time you popped another 3oC, and so on and so on until an exotic drop was virtually guaranteed, one dropped, then your chances dropped back to normal. With this booster you should have the chance to get more exotics than we used to have drop in the same amount of time farming. If you nerfed the chances of exotics dropping so far that the new 3oC booster is less effective than what we did before, it is not worth the shards required to buy it. Make it worthwhile or get rid of it DMG04.
