This is a great move on
MA part, but when I play its easy to stay for way longer then 6 hours, instead of a disqualification maybe the points should not count and maybe even a message stating your points do not count towards the events.
I know you have a feature that tells players how long they been online for the session but that does not work if the player ctds.
I have been knows to stay online for 3 to 4 hours at a time take a break and come back for another 3 to 4 hours so that would have me online for anywhere from 6 to 8 hours per day, I would really prefer that the points after the 6 hours did not count towards the event and a message (like a auction one) was given to me that points do not count, or at the very least a message stating that I need to log off if I want to not be disqualified from the event.
ATM I’m retired disability so guess this shows I have darn to much time to spend in

Back in the day when I had no life, I used to play
