That's not a definitive line, at all. That is completely arbitrary. What is a set schedule? What is off and on? These are all completely meaningless.
You think theres 16 hours of content to do every day if you just do solo and queue content?If you wanna call the guy that logs on 16 hours a day to do every single daily and farm achieves casual because he dsnt manually form groups, you do that lol
My line makes sense. It's a hard, objective line. It's not a bunch of wishy washy bullshit that anyone can move around to make mean whatever they need for their argument that minute.
