This is patch to differentiate Athens civilization.
Discussed in the forum balance group.
How athenas should play:
Athenians have access to all the naval technologies including several special unique ones and a civilization bonus that specifically decreases their ship construction times, and a moderately powerful and effective navy much like all Hellenistic factions.
Athenian Infantry are fairly well armored and versatile, with effective citizen solider spearmen and skirmishers along with specialist late game champion units and having access to the powerful Phalanx formation for melee infantry.
Although lacking in the Battering Ram, they possess effective siegecraft with Stone Throwers and Bolt Shooters along with their upgrades.
Well rounded Cavalry, with access to very effective raiding cavalry to harass enemy support units and chase down weak and vulnerable infantry.
Athenian Walls are some of the best available, with strong stone walls and wall towers that can fire on enemy troops while also with a special technology allowing them to be built and extended into neutral territory.
