Crota is a fun raid and I will run through it with any 27+. Find good people and have a good time. I don't care about the drops. I beat Crota last Tuesday and probably joined about 50 other fireteams to help them out. Makes the game exciting trying new strategies. The only thing I recommend to players that have not played Crota or are new to it, get tracking rockets no matter what level they are. An uncommon rocket launcher that tracks is 100x better than a legendary rocket that misses him by 200 feet. You get tracking you will be fine
