To counter point that, a fresh group of i117 people is more than capable of farming full suits of alluvian and getting full i119 in <1 day. From there they can start zi tah, and again, in less than 1 day replace that full suit of i119 alluvian armor with i119 zi tah armor.

Why not skip the middle man and go straight to zi tah, 1 decent i119 can usually cary a group of i117 RoE people through enough zi tah NM to gear up.
