Why did the Age of Empires not become an e-sports discipline?

Hello. I'm a big fan of real-time strategy and used to play a lot in the Age of Empires. This is a great game, but it did not become the eSports discipline.
A number of tournaments were held on it. But if you compare the Age of Empires with the cyberscene scene StarCraft, the difference is very large.
I will describe my thoughts, why it happened.

1. Variety of game sides: there are a lot of game sides in AoE. But all of them differ only in a few unique units and bonuses for the faction. In the SC there are only 3 sides, but each of them is unique: each unit has its own peculiarities, strengths and weaknesses and it does not look like representatives of other parties.

2. Balance system: taking into account the feature of the troops, the player needs to constantly explore what kind of technology the adversaries have gone and build troops that will defeat his strategy. There are many technologies in AoE. But their development is fairly linear. After studying them, the troops simply become stronger and there is not much significance to what to study.

3. Map: In AoE, resources are scattered evenly on the map. And usually it is sufficient to develop one large settlement in which it is necessary to develop the collection of resources and the production of troops. The relief of the map almost does not limit the passage of troops. Because of this, the map has quite a few strategic positions that need to be kept. In the SC, reserves of resources are concentrated in certain places and it is necessary to create and develop new bases for their extraction. Their appearance makes us expand the front of combat operations: the player needs to protect the city in different new ones in different parts of the map. The passage to many locations is limited by narrow aisles. In this regard, the retention of these passages is of great tactical importance. A choice of position often determines the outcome of the battle.

And yet I'm a big fan of AoE and the themes of the Middle Ages. I hope that the authors of the new part will be able to develop the experience of the SC and make it into the AoE.
And do you think that will change the mechanics of the game in AoE 4? And do you know other games about the Middle Ages that have a game mechanics similar to the SC?
