I want to keep this short and sweet.
In my decade of playing this game, no content has been so thoroughly boring as the combat loop of killing standard enemies just to have another wave respawn and repeat the process until the game feels like it has adequately wasted your time. It was a major bore during the KOTFE story with the skytroopers, and continued in the Echoes of Oblivion during Onslaught. This needs to be addressed before SWTOR story content slowly morphs into nazi zombies.
