I've mentioned this from day 1. In custom battle they are the weakest nation.. on every category.
in the campaign they are weak because of the following things:
- weak or wrong skill setup (for example druzhinik got 160 bow skill and 60 polearm.. they dont have bows and polearm is their main weapon....) Ulfhander is 2H main, but got 80 in 2h while they got 130 in pole, which again they dont have. They are a tier 5 unit with no armor but have athletics 130 instead of running OP Fast and attacking fast like crazy they are without doubt the worst tier 5 unit in game. (For comparison battanian Fian got 160 athletics and full armor) IMO the ulfhednar or berzerkers should run crazy fast and attack crazy fast as well. It shouldn't be possible to 1 v1 a berzerker, however in my campaign they get easily mowed down by a tier 2-3 unit as if they are a simple recruit. Also because they have no armor they should make zig zag moves with high run speed to have at least some advantages.
- weak gear Tier 5 units severely outclassed in armor compared to other nations, even the Khuzaits which should IMO be mainly light armor have more heavy armor (and even more heavy infantry) than Sturgia (which is supposed to be main heavy infantry class. (Guess the developers really hate the Sturgians..)
- Compared to Battanians and Khuzaits they got to run long distances to replenish... The Khuzaits which should be nomads (Few cities spread across vast distances) got more total fiefs (49 villages,castles, towns) than the sturgians,, which are a settled nation. And all their villages are tightly packed together. Khuzaits got more fiefs in 65% of the landmass the Sturgians got.
- Horses cost no food and can outrun AI lords in wars, resulting in Khuzaits ganking AI lords with 500 vs 100-150 non stop.
- snow doesn't give attrition to enemies, nor does it slow down units...
All in all the Sturgians are by far the weakest faction in the game.. and only by heavy intervention of the player do they survive more than 2 years ingame.
