I´ve decided to kepp the wraithlords. The main reason for this is that I don´t have enough wave serpent models to go fully mech though
, but I agree with Irisado that they'll be tough to kill even with rending weapons (hopefully).
I'm completely droping the banshees in favor of that second fire dragon unit. As for my unit of choice for the anvil, I think scorpions are the best bet because of my overall lack of dedicated cc. Hopefully this will give the anvil enough consistance to make the guardians endure the whole game, as I will be running short on troops.
As for the farseer, his new role on the battlefield could be to acompany and guide the avengers, and also doom whatever they will be shooting at. Keeping the fire dragons close enough would maybe give me the chance of guiding them instead depending on the situation... I assume the scorpions will be too far back to also benefit from doom, but in their counter charge role they should only be charging softened up units anyway. I don't know how good it is to drop fortune, as it really does make me more confident when moving the serpents at full speed towards the enemy. Finally, when you talk about runes of witnessing, do you mean the more expensive ones? That´s what I think, but I wasn't sure as my codex is not in English.
I'm reluctant to add another bright lance to the serpents because they would already be carrying a dedicated anti armor unit, and I feel that would just be too many eggs in the same basket.
So with this in mind the list would look like this:
Farseer, runes of witnessing, stones, guide, doom 130
10 guardians, warlock, embolden sl 125
10 avengers, exarch dual cats, bladestorm 152
Wave serpent, stones, bl 145
6 dragons 96
Wave serpent, stones, shuriken cannon 110
8 dragons, exarch, db flamer, crack shot 145
Wave serpent, stones, shuriken cannon 110
8 scorpions, exarch, claw 155
Wraithlord, bl eml 155
Wraithlord, bl eml 155
I would like to completely flesh out the scorpions, but I just dont have the models... so with those 22 spare points I could get a singing spear, upgrade the serpents to sl instead of sc and buy one more guardian.
