But running with randoms, taking the time to be patient with others, being able to adapt to differing playstyles on the fly, being able to explain mechanics in a helpful and considerate manner after several wipes, those are the things that makes a mentor, and because of the way you conduct yourself, you earn the commendations needed for the status.
While I main WHM, I still earn commends when I BRD, SMN or NIN, because I try to be friendly, I ask if people need tips before fights, and after wipes I don't lose my rag with anyone, I simply calmly ask if I can offer guidance in a constructive manner, and do what I can to get the clear.
It costs nothing to be friendly and helpful, but it pays well.
