I understand that it is random, but either i'm the unluckiest person in the world or something is broken. I have done the vault (only one and a half times) rank 3 for crucible, rank 24 with the cryptarc, 3 vanguard, 1 fwc (not bragging, just establishing i wasn't sitting at the loot cave for 216 hours) The only exotic anythings i've got i had to buy from the weekend vendor or do an exotic bounty for. This game hasn't left my xbox since day 1 and I play everyday which wasn't so much of a problem until I saw a person get an exotic weapon from the crucible and when i looked at his profile he had only been playing for 25 hours. Ive decoded a thousand engrams and the best i've done is getting 1 purple cloak from a blue engram, i have had a few legendary engrams that were turning into legendary stuff in the first week but after that pretty much all legendary engrams turned out blue items Hopefully bungie reads this and implement something to raise the chances of getting exotics and legendarys for anyone that has put a lot of hours into the game and aren't getting rewarded
