Thanks for your comments!
Playing around with the army composition all the time at the moment, while I wait for my latest purchases (a Ghost Ark and 2 boxes of Wraiths) to be delivered. The small teleporting Stormtek unit is gone (it would basically have been a more survivable "meltacide" squad, by the way. Hop in, kill the scariest thing with an AV in the enemy army extremely reliably, and then die), along with several other things I thought about using. Specifically, I don't think Tesla is any good on immortals considering the current rapid fire rules, and I don't think Necrons need dedicated objective campers. This ain't the guard! We can easily just beam troops on objectives from a Scythe when it's time (invasion beams rule is freaking awesome!).
Annihilation barges remain a staple I think - they are just such an efficient way to get a ton of S7 shooting on a quite sturdy and mobile platform. Math says they should do okay against flyers even without skyfire, yes, and also be able to damage pretty much anything else short of AV14. 2 of them is 180 points, for 2 twinlinked S7 heavy 4 guns that generate 2 extra free hits on each 6. Oh, and one non-twinlinked S6 heavy 2 gun that also generates the extra hits on 6. That's a lot of hits on average, and potentially up to 18 if you roll all 6s. For 90 points each they're a complete steal in my opinion. They are what a Dakka-Predator wants to be when its grown up.
The main thing I'm considering changing is using the Dark Harvest list from IA 12 as my primary detachment, with a small regular Necron allied contingent. What the Dark Harvest list offers that intrigues me the most is a fearless character with very good combat stats (Kutlakh the World Killer). I'd like to use him to make the big Phalanx of 20 warriors more reliable - normally they're very susceptible to being swept in assault, with Kutlakh in the unit that won't happen. And 20 Warriors that don't run and keep getting back up sounds awesome! Also, with the IA 12 list I can buy an upgrade for Warrior units called Flensing Scarabs. It gives a unit Shred in the first round of close combat they fight. Kutlakh is also a Phaeron, which gives relentless. So his big Phalanx can charge after rapid firing, and with the Flensing Scarabs, their boss and their numbers they should even do a decent job!
I can post an updated list if you're interested. Concerning the fotos, well - the friend who wanted to bring her camera was the one who broke her clavicle on the weekend we wanted to do that (as mentioned in the unhappy thoughts thread). So yeah, pics later I'm afraid.
