Infantry is dead slow, and for fighting on an open field, you need it. One downside of Gorgo is that her talent tree is not that great and she does not have marching speed. Based on her skills, she looks like she can be used in an open field, only one of her skills does not work in an open field. If you are a free-to-play player who is defending objectives and has a strong commander to pair with her and infantry gear, then feel free to invest in her. So if you are a pay-to-win player, you should definitely invest in her. She is currently one of the best commanders that you can use for degrading objectives.
Gorgo is an extremely powerful infantry commander. She has the Infantry, Garrison, and Defense talent tree.
In Rise of Kingdoms, Gorgo is a Legendary infantry commander.
