lictors, neurolictors, and deathleaper. whats the gameplay/role difference between them? the various use cases etc, and are they good? i was thinking about getting 2 lictors, 1 neuro, and DL. would that be pretty good in a general purpose nids list? the models are sick.

also, i have a GSC army, do these guys work for that vanguard organism subfaction?
