Weeks????? Hours I'll give you that. This was a season, not a dlc so of course you had to grind for the endgame. Seasonal content is supposed to add to the endgame grind, that's why they exist. If you play three characters and ran every milestone you could have been at 1050 legitimately with one character and the others would be on the upper 1040s. I heard the already patched the exploit. I actually tried it out earlier with my first character the play some armor catch up, think I tried 2 or 3 hours, maybe got 5 or 6 engrams and not enough mats to upgrade them all. It wasn't efficient, could have gotten more engrams add mats for upgrades playing that three hours.
