This weekend after launch I was able to get 1 key per 7ish events. But at a 6-7min wait between chest rewArds and the next event that is about 45min to an hour just in waiting time, then add in the actual fight that can take 3-6min it's self depending on the number of people adding in almost another hour... So that was 2 hrs for one key... And that isn't even counting the fact. That the average chest had to be looted 2-4 times per event depending on its location bringing my drop rate to 4.7%. Today the 26th iv just finished with my 12th event and not only do I not have any keys but not even any legendary engrams! So after 3+hrs nothing! Why bungie!? Why would you lower the drop rates for the only way to loot in the dlc! VoG after the same time had already given me 3-4 legendaries or even an exotic, this current system makes me sit around for an hour or 4 to get a key that opens a chest at the end of content that will take another hour or 3 just to get a single gun... (Depending on digiculty lvl) .I have farmed around 15 keys since the dlc launched and I gotten the full set of te queens guns, 2 crap hard lights, a universal remote, and then duplicate queens guns... So potentially 5 hrs of "work" or just if my day and I get one real item out of the prison chest. This is a horrible ratio bungie! Please let the keys have a greater drop rate from the chests or at least from the lvl 32 and up prison bosses! There is almost no incentive to play the PoE without a key and I don't want to sit around for 3hrs trying to farm one! (I am also not fond of pvp or rather the thorn show so pfft to the trials, fix the only thing on your game that is for solo players to get good loot!
