My gripe with this complaint is that invading Garlemald had to happen, due to the existence of the Tower of Babil, and I got the impression that they were trying to minimize unnecessary casualties. I agree that expecting hostility without a single casualty would be unrealistic, but military operations with the goal of minimizing them has always been a thing.
Yeah, to be honest, the game constantly forgets the Linkshells exist. Every time a mission goal involves "Fast-travel to X location and talk to Y character", I have to question why linkshells suddenly aren't an option for the character.
