KoR are overpriced by this margin.
5 Warrior Knights with lances cost 255+35 = 290
5 Knights of Ryma = 340
Knights of Ryma have 2++ with fire, LR, +1 move, +2 Agi and MD
Warrior Knights have 5++ with toxic, +1 Res, +1 Arm, Fearless, +1 Att (all rounds) and +1 Str on horse
(+ they can be tuned with Flavors for extra cost)
They are more or less equal. Knights of Ryma are better glass-hammer, but Warrior Knights grind and survive better.
So difference between their points should be 10-20 points, not 50 points.
