He does? Because I sure as hell don't see one. He needs a monolith because he's a necron player? Sorry, I don't see the argument here.
So, I think I'll put a rest to that, and move on to the list. I don't feel like reading every single comment made, but I have the general gist: less HD, more D, axe the FO, etc.
Lets start with destroyers. Three HD's are extremely hard to kill without diverting a significant amount of firepower towards them. Put them about 5" from each other, nothing will hit more than one of them, except a Talos, unless it hits everything along a straight line. 5" is enough for WBB range, and with clever positioning, you can't deny the WBB without killing all three of them. Your destroyer unit is fine as is, since finding the points for more would be pretty hard. The one suggestion I would make would be to drop 4 warriors, consolidating into three units of 12, and two flayed ones (they are often overlooked for their lack of shooting), then get two tomb spyders. You would be at 1501 points, and putting a spyder by the destroyers and heavy destroyers would make it damned impossible to kill them with the aid of that destroyer lord of yours.
Kudos on the flayed ones and scarabs, they are both highly underrated. True, scarabs will do next to nothing most likely, but they cost nothing too. They are amazing for keeping those assault units away from you. They are small, but with 3 wounds each, you wouldn't believe how long they live. Flayed Ones are cool, because everybody thinks necrons = shooting only. I have had units of flayed ones take out units of terminators. They are much better than warriors usually, since they can infiltrate or deep strike, and are more useable in assaults.
Also, feeback from you, rIzA, would be great.
