Maybe I got lucky, spent a few hours in learning parties to get my first kill; spent a few hours in "close to clear parties" to hone in on the mechanics/dodging of the fight; then went straight into farming it. Had the mount and armor pretty quickly, (guessing in about 80ish pulls). Honestly the most "extreme" part of the duty was weeding through the "Farm Party" PF traps to find a solid team to knock out 5-10 clears with in a row.

Oh, the moment when your farm party queues in and the other 3 members are "viewing cutscene" and you get the notice for bonus first time clear tomes..........
