1) you should probably change megachad to megavirgin.
The only useless Sturgian unit is a Spearman, this unit has no value, role. It does not have any application in the army.
My Sturgian party of 340 units kills 1500 Khuzait army while losing under 30 units total.
SHA has an average KD of 10.
DC has an average KD of 12.
Sturgian Archers are good enough to serve as bait and as anti-cav units. Their kd of .09 or 0.8 is sufficient for their role. They are not your top killers.
Sturgian Heavy Axeman can kill everything in the game if used properly. Which includes formation, use of ranged weapons. Mind you these guys carry very powerful javelins. Javelins which SHA can use in melee as a spear.
I rarely use Linebreakers even if these guys can demolish Legioneers. Because in the current state of the game Linebreakers should be placed in their own group and I don't want to bother.
Raiders... i no longer use them because they only carry 1 stack of javs and their polearm skill is not high enough to be effective.
Your tears about shocktroops are silly. shocktroops were dying to T2-T3 melee units because AI can not use range of the weapon properly and attack speed of war razor is abysmal.
And yes I'm playing Sturgia way longer than you. And i could understand the complaints about economy, terrain and travel time for armies. But you complain about units, that's pathetic.
