Deathmarks - roll to hit on a 6 choose the hit model.
Gauss - glancing on 6s so insane anti-tank
General necrons - take models closest to shooter for wound allocation, good to keep enemies away from you, overwatch helps to soften an assaulting squad, and if it contributes towards combat res then even better, and finally random charge length to stop people assaulting.
Necron warriors - move and shoot with rapid fire is very useful, I think relentless gives u an extra shot with a rapid fire weapon, maybe not as effective but still very useful with a phaeron if rumours are true.
Destroyers - new preffered enemy very useful for shooting, especially with heavy destroyers because I never seem to hit with those. What's more the fact you can move and fire heavy weapons is even better with heavy destroyers.
Trazyn - maybe a bit worse with the warlord perks, could make his objective capturing a but less.
Command barge - the sweep attck isn't as unique anymore with the vector strike
Scythes - much better, hitting on 6s if shooting at it, a lot less killable.
General vehicles - most necron vehicle have 3 hull points which is pretty good given a land raider has 4.
Me: To be honest im amazed there isn't a chaos god of not revising or at least chaos god of procrastination
MidnightSun: There will be, when enough people do it. Y'know when the Eldar were all engaging in their hedonism and Slaanesh ripped open the Eye of Terror with his creation? Slaanesh will have NOTHING on the God of Procrastination, and his vile minions will carve the galaxy asunder in a thousand year reign of blood.... Tomorrow
