So, I am thinking of leaning to a destroyer heavy force. Due to the UNLIMITED POWER and the speed and such. Also, I really like destroyers, I think they are really cool.
I am thinking of this as a list.
x2 w/Particle Projectors
It has been through one game so far, against Deathwing. The Destroyers managed to whittle down the Terminators pretty good, and immobilized both landraiders quite quickly. The army has 24 points left anyway, so I might just give one warrior squad D-feilds, or add one more warrior in..or something.
The immortals I've found are also quite fantastic and unleashing a hail of shots, and their high toughness is great. The army fell flat when going up against the Terminators in combat, which is something I really could not avoid (due to my slow warriors, and my Lord dying early by being charged by terminators). I feel that even through that, it's fairly solid. I am thinking of a couple possible alterations.
1. Dropping one warrior squad for a Monolith. Helps mobility of the warrior squads, and is a big threat. Also, the Particle Whip can be useful at actually 'destroying' vehicles. However, it's fire output is not too great, nor is it's mobility on it's own.
2. Swapping the Lord for a VoD res orb lord w/Warscythe. Still has the Scythe for melee goodness, but is able to reposition my warrior squads when needed, or suck me out of combat. Doesn't share the same toughness and reach of the Destroyer Lord though.
For 1750pts, I would most likely Toss the Monolith in anyway, as why not. Or, a few squads of Flayed ones to outflank/infiltrate to cause a distraction.
Ideas on the 1500pt list, and expansion to 1750 is what I am looking for in advice.
