Hey thanks for checking! so it's quality more than quantity? More raids and a Gjallahorn will appear? looking at Destiny Tracker the top guy has done 56 raid but spent 68 days (1632 hours?!?) on the game! he must be a pro. I actually clocked 24 days (600 hours) from their data so not sure which one is which (bungie vs DT). Anyway my point is that whatever you do in the game, once you pass a certain amount of time playing it, you should be rewarded with most or all the secret items in the game. This is to reward the time spent and to make the game more enjoyable, if the answer is more raids than I guess that's the answer (ps 6 people raids have always been difficult to complete without a good team, hence the lower number!)

Your chances at exotic drops are much higher in the raids. You are handicapping yourself by not playing them. Don't complain about not getting the exotic you want if you don't even complete the necessary steps to aquire them.
