I think two squads need to fill this roll in wave serpents, scout up and jam down that serpents shot in the thoughts! then turn 2 jump out and hug a wall or cover then pounce them with both squads, the exarch is a BEAST! Killed half a squad by himself. that ap2 claw is too good not to take.
Farseer support are mandatory for this setup and dire avenger minimal squad size in serpents is the way to go.
In this list I also took hawks which I liked, haven't used them as much as Spiders for they are too good not to take but I'm trying to vary my army choices nowadays.
Here is the list I have using:
Farseer
Autach, Wings, Fire Saber
Striking Scorpions w/e Exach, Biting Blade w/ Wave Serpent w/ Scatterlasers, Holofields
Striking Scorpions w/e Exach, Claw w/ Wave Serpent w/ Scatterlasers, Holofields
x5 Dire Avengers w/ Wave Serpent w/ Scatterlasers, Holofields
x5 Dire Avengers w/ Wave Serpent w/ Scatterlasers, Holofields
x5 Hawks
Wraithknight Suncannon, scatterlaser
So this is a smal list I've been testing. Observe that all of the models are WIP.
See you guys!
