well well well gw adds insult to injury with the first data slate which was shocking their was some interesting ideas but none of the formations were any good.
and then gw pulls out the skyblight swarm formation BOOM! that's what im taking bout endless swarm loads more flyers and gargoyles are troops and they can capture even if contested it makes for a very fast army its what nids have really needed.
and then living artillery formation more big heavies added to the army with warriors now serving some function to give preferred enemy to exocrines and biovores.
now with these additions nids can take on the big boys at the top the problem is its not obvious their is no 1 click unit or trick it takes hard work n skill although either formation will help loads so lets take the list n add a formation
now im not sure on points but 5 FMC and 4 normal MC that's lots of heavy duty as well as lots of bodies so now nids are looking pretty strong u can even change up the fast for a slow heavy walking list.
so try out the new formations their well worth it
