So It took me quite a while to come with a list that was balanced, not spammy, and was generic enough to not better fit another theme (like a more craftworld oriented list, or over shooty/assaulty). I wanted a good mixture of foot units, that can work in a take all comers list. Not exactly "competitive", but should win against other like-minded lists. Most of all, it had to also be fun!
Avatar (195)
Farseer (100)
11x Guardian Defenders - Bright Lance (119)
10x Guardian Defenders - Bright Lance (110)
3x War Walkers - Scatter Lasers (180)
Wraithlord - 2x Bright Lances, 2x Flamer (160)
Wraithlord - Ghostglaive, 2x Scatter Laser, 2x Flamer (155)
Aspect Host (+1WS)
6x Swooping Hawks - Exarch, Sunrifle (121)
10x Howling Banshees - Exarch, Executioner (150)
10x Striking Scorpions - Exarch, Scorpion's Claw (210)
This list will run mostly as a Phalanx. Hammer and Anvil could work also. The Farseer will join the 11-man Guardian unit and support with powers based on the opponent. Likely looking for fortune, guide, prescience.
The Avatar and Wraithlords present the enemy with a big scary target to worry about taking pressure of the little guys. Most units can make good use of the Avatars boost bubble.
I have 4x anti-AV13/14 shots for those single LRs/Monoliths/Wagons etc. The MC melee attacks, and Hawk haywire can also help here. Plenty of anti-horde/infantry fire power with the scatter laser shots, that also double as light anti-armor and anti-flyer (with guide). Hawks also help against flyers as well. Two dedicated assault units will help as the enemy/I draw near towards the midfield.
