The Disciplle of the Pike focuses on two fighter weapon groups; spears and polearms (ingame this translates to spears of all kind plus javelins, and bardice and glaive). The class gains bonuses to such weapons, which can be seen when you read the entry of the archetype's Pike Charge ability. However, when you look at the archetype's Weapon Training ability the ability only benefits the spear fighter weapon group rather than both spears and polearms fighter weapons groups. This is different compared to the d20 ('paper') version of the archetype. Is this an omission or is it intentional?
