Make Alexander Great Again
When playing as Macedonians, who actually chooses Alexander the Great as their preferred hero? From his conquest, Macedon quickly became the largest ancient empire! People looked back on him for generations as OP. I think he should be THE or ONE OF the top heroes of this game.
10% Territory increase doesn't help you much in the game. Especially since, IIRC, your territory's ability to take over enemy territory is diluted by how large your territory influence is.
I've tried to use the CC capture thing to my advantage, but haven't found it very strong. You pretty much need to damage the enemy CC no matter what, which is fair. It is a cool idea, but it can't be his only thing.
Attack bonus vs other heroes is a cool minor perk. Still weaker than Cleopatra's health de-buff.
I propose his benefits be:
Alexander
Counters: 1.2x bonus vs Heroes
Conqueror: Enemy Civic Centers - 50% Capture Points Garrisoned Regeneration Rate. 60 meters
Inspired Defense: When garrisoned, the structure has +2 capture points garrison regeneration rate.
Imperialism: Structures + 10 Territory Influence Radius
40 Meter Aura: Own Soldiers (not siege) +10% Ranged and Melee Damage.
He wasn't just some guy who captured buildings. His army kicked butt on the field. (Same rationale for below)
50 Meter Aura: Enemy units & Structures -10% Ranged and Melee Attack Damage
I think this is better than an armor boost because it emphasizes his active role in battles. He can't sit back behind everyone to get the benefit. However, I wouldn't want it to promote "dancing." An alternate would be Own Units + 1 Hack/Pierce/Crush Damage.
If these benefits seem to make Philip II irrelevant, maybe his aura could be changed to a Pikeman bonus, since I believe he was the one that the whole pikeman thing going. I don't feel strongly that this is necessary but here is one idea.
Philip II
Rise of Macedon: Champions + 2 Capture Attack, +20% Ranged/Melee Damage
Pikemen + 100% Melee Damage
