We farm because of the 6 legitimate legendary engrams that have dropped (or given when leveling up the Cryptark), I've received exactly 0 decoded as legendary . . . lots of rare which is usually less than the rare I'm already using . . . extremely disappointing. I mean, at the rarity they drop, I would hope that the conversion rate would be much higher than 0% in my case . . . hell, even one conversion now would put it below 15%. So very rare drop, with very rare conversion equals lots of time grinding/farming . . . and to tell me to run the Nightfall strike isn't the solution, I'm not leveled high enough to make a run at it and need better equipment to do that . . . I try to max out my vanguard marks, which is where my one piece of legendary came from, I bought it after grinding out enough missions to get it.
