I'm a huge necron fan so here goes nothin'
PROS:
- Best general gun in the game thanks to the gauss special rule. Can glance or wound almost anything on a 6
- Several cool shooting options (Destroyers have ap3 guns, guass, tesla)
- Several cool melee options (Wraiths, Praetorians, Lychguard)
- Wide range of unit types (infantry, jump, beasts, flyers)
- Super resilient thanks to reanimation protocols
- A bunch of really good formations
CONS:
- Can be swept easily if
RP doesn't save your butt
- You'll always fail a blind check
- Unless a unit is really good at melee don't count on it doing much in combat
- Very few weapons fire more than 24"
- No template weapons to speak of except for the doomscythe and doomsday ark
- No psykers
- Only one land based transport
- Flyers can't hover
- No way to remove cover during shooting
- Allies table is not that great
I'd say the lack of psykers are the necrons biggest failing. We can't participate in 1/4 of the game.
