This removes the Champion training aspect and reduces the GarrisonHolder from 2x to a 1.5x bonus, the same as the health and capture points bonus. 2x garrisoning caused there to be a prohibitive number of arrows.

Replaces the champions with faster batch training speed. Unlocked heroes still remain.
