I never grinded once. I got gally third week, thunderlord third week, icebreaker the first time he sold it week 4 or 5, fatebringer, VoC and praedyths within my first three hard mode runs. Vex i got before its first nerf by a single day, and most of crotas end gear i got the BH first run. Now armour, thats a different story. Didnt get a helmet of even exotic for my titan until 3 weeks from dark below. Then it was a month and a half before i got one again in dark below.
