I've just noticed:
Winged Lancers are 3 attacks, 3 hits and 5+ armour for 100 points.
Cossacks are 3/1 attacks, 3 hits and 5+ armour for 95 points.
Cossacks have a shooting attack for 5 points LESS? That can't be right?
Should Cossacks be 110 points?
Edit: Also the Red Guard have the same stats as Cossacks but are infantry, yet are only 5 points cheaper than Cossacks. Another indicator that Cossacks are underpriced perhaps.
