So how the the local nid players finding the codex after playing a bit?
I haven't used it but have read the codex extensively, it doesn't look at bad as people thought. The gripe was mostly with loss of option choices, which I still agree.
Warriors and Genestealers are a lot better then people think, and certainly better then the guants, but you'll obviously invest more points for them.
Deathleaper+Broodlord+ SotW is probably the most powerful debuff in the game, it just may be tricky to pull off.
All the heavy choices are really good, and from a tactical perspective I think the Harpy/Crone is pretty good too.
The army requires a lot of synergy, even if you don't take IB gribbles, but still has a lot to offer.
