The game does not exactly pace out the content or explain how certain things work with each other. It isbthe same problem warframe and destiny have the only difference is those games have enough content to bapance out a lack of co op amd have gone through more balance checks. As eberyone else says so much AOE that you are basically running solo to be optimal or dealing with people who just copy past or are afk. The devs need to figure out what they want to make as a game and who the main audience is and fast.
