I madified few units' parameters in order to valorize their role letting intact what are their dynamics.
Spear Cavalry has now a bonus multiplier against cavalry units marking their role as "charger" units wheter in battlefield or in commando raids without altering too much the previous balancing decisions. F.e. now spear cavalry can outdamage a sword cavalry without compromise the sword cavalry role of "ranged units stalker".
Infantry Champion Spear has slightly lower attack rate giving a more relevant role to champ swordman in infantry fights.
Wardogs could deal more damage before being killed (i think that they can still be improved but increasing armor to a population free units didn't seem a good solution).
Pikemen can move faster and deal a bit of damage more in their 2 seconds attack rate.
Mauryans have an unique unit which is the elephant Archer which could have a solid constitution typical of elephant units.
War Elephants looks like they keep busy units for too long time making even wider the gap between them and siege units.
