I like what SE did when they introduced the daily roulette. The one who helps has an incentive to do so (GIL, EXP and tomes) and people who actually need to enter an instance for character progression need to wait less and have a better chance to beat it.

But I also know that some don’t do it to help but to get their tomes quicker and sometimes these people rush groups and act aggressive if the run is not quickly and smooth.

I also heard from people I met in dungeons via DF that they are afraid to enter certain dungeons because of their experiences with toxic people.

So how about introducing a Mentor role?

When you enter DF (normal instances and Duty roulette), you check a checkbox and apply for a Mentor role. People who need help with new dungeons could search for instances where a Mentor is available. The search might take longer but they can be sure there is somebody there to help if they have questions. The checkbox could be placed under the already existing one where you include ongoing instances in your search.

Shy and inexperienced people would have the Safety that there actually is somebody who will help them explaining at least the Strategy and additionally maybe even providing useful hints about skills and how to play a class better.

The Mentor would, in opposite to Duty Roulette, not only go there to get his Myth tomes quickly but to actually really help people. I know the helpful guys are out there, seen them, been one of them.

As an incentive for the Mentor I suggest that he gets, independent from the actual votes in the dungeons, an extra commendation for being helpful. Maybe double the votes he gets from the rest of the party as a bonus. I leave it up for discussion whether there should be even more incentives like more GIL or EXP on runs below Level 50 and a few tomes for Level 50 runs.

My stand is that if you want to help others, you do not need extra incentive because the good feeling that you have when you know others had a good time thanks to your help should be enough.
