It is a reflection of your experience in mythic plus:-
- it shows the highest key you have done, whether that was on time or over time
- it shows the role you perform getting the score
- it shows the score of main on alts to indicate what level of understanding you have of the dungeons
- it shows the number of completed runs in brackets so you have an idea if this person has just done 1 timed run or loads
- it shows the leader the highest key youv’e done in the key you are applying to
- it gives score based on the level of your key and whether or not you timed it, how fast you timed it or how much you went over by
This is not an exclusive list.
If you are applying to any group you don’t have a right to be invited, you are just listed to be considered by the leader. If you play a role like dps you are going to be up against a sea of applicants. With higher keys the group may be looking for a specific class or ability, we will see more of this in SL with covenants coming into play.
