Do the 3 ground pieces from this set still drop from the reward requisition boxes on Nukara? I have yet to see a single piece after opening about 60 advanced boxes and maybe 11 or so elites. I usually see enviromental suits or a sonic ranged weapon as the reward... the shell pieces must be stupid rare.
If they -do- still drop, is there anything I can do to increase the chance of a shell piece from the reward box? Seems like a decent alternative to some of the other armors out there, esp with the augmentation lobi option. Any tips?
