Its not really even about helping others improve..... The goal is to complete the mission assigned. FINISH THE RAID.... why leave and waste everyone's time.... just because your tome farm is being delayed.

If you opt to do a Duty Roullette, then you are opting for whomever queues up with you to be your compatriots!

IT IS COMMON DECENCY TO ATTEMPT TO FINISH..... even if that means struggling through 90 minutes of failure... Majority rules, if you disagree... you are welcome to leave.... and the 30 minute penalty is the consequence of your selfish actions
