Thanks for the run down @Yoshiya some really valid points! "Puzzles in list building" certainly sums it up, making efficiency decisions and substitutions leads to me almost being better off playing stormcast with some allies but I would really like to get a nice mixed Anvilgard army to at least an almost competitive level. I've reworked it into the below;
Allegiance: Anvilgard Mortal Realm: Ghyran
Knight-Heraldor (100) Lord-Ordinator (140) Knight-Incantor (140) - General - Trait: Inspiring - Artefact: Wand of Restoration Sorceress (100) Battlemage (120) - Specialisation: Jade - Allies
10 x Darkshards (100) 10 x Warriors (80) - Axes or Hammers 10 x Warriors (80) - Axes or Hammers
20 x Sequitors (400) - Stormsmite Mauls and Soulshields War Hydra (180) War Hydra (180) Celestar Ballista (100) Celestar Ballista (100)
Prismatic Palisade (30) Everblaze Comet (100) Suffocating Gravetide (30) Soulsnare Shackles (20) Total: 2000 / 2000
Heraldor is a great point being able to retreat and re-charge in a better position is going to be a real asset.
20 sequitors is just too much value at current costs to change they will be my core front line.
War hydras are there to contest the flank objectives or help hold mid against khorne, eels, or daughters with the support of a jade mage and wand of restoration.
I've dropped one unit of shards and a sorcerer and split the warriors into 2x10 to fulfill battleline these are my third wave v melee centric armies or (slowly) push the flanks behind the hydras. Sorcerer is still the primary wall caster with +2 from a sacrifice, I can't imagine anything worse than all going to plan and failing the wall cast roll.
I've kept the ballista ordinator combo for now I have just had too much value out of these and have found deploying them aggressively and creeping forward the 3" every turn they can get good use out of the rapid fire. When they get point changes or if I can't make this army work they'll be on the chopping block. They're also my only source of rend -2 or better which not having has hurt me in the past v slyvaneth and lizards.
I have gone fairly gluttonous on endless spells, if people have used the Aetherwings to any effect and found them worth 50 points I'm all ears and would drop gravetide and shackles for a flock.
