Isn't the Heroic Line Breaker meant to be the shock trooper melee monster?
Apologies if that wasn't angry and/or rude enough.
I like that Sturgia has two offshoots of shielded heavy infantry, it makes them more unique from other factions in my opinion.
And having a spearman with a shield fits in well with Sturgia's Kievan Rus' inspiration.
As an aside, it would be nice if the two shielded infantry looked more distinct (and more Slavic) by having differently shaped shields. Right now both Heavy Axemen and Heavy Spearmen get the same size/shape round shield.
