The idea is that when a pikemen goes to an enemy it instantly damage enemy in process and still gets to attack because its not like your gonna rush to the enemy with your spear down
Also works when enemy goes to you
When you go close to a pikeman you will get damaged (full damage and bonus)
To improve the effectiveness of polearms against cavalry cause a maxed out cavalier can just charge to a maxed out halberdier and kill him making cavalry more powerful in AoS
Because in real life cavalry can't go close to polearms cause they'll get damaged in the process
And makes polearm units strong enough to fight other melee units
And maybe add this to peasants cause why not
And makes the lancer and upgrade able to charge cause it will instantly dmg unit it goes at at the same direction he is going at
If unit is went up north then the enemy up north of that position recieve the damage but if there are enemies at the side those enemies will not receive dmg, dmg if there is no one in front at the location it went to it will randomly chose from the one of the enemies nearby at that position
