Yes because you have to have flying to do mythic raiding. You didn't get everything you needed to unlock flight while mythic flying? Tsk tsk.
I see calling people and things self-centered is the new way of attacking people who say things that don't fit your narrative. So it is okay to have chests to open because other people like it but if -you- have to do something then holy hell burn down the church! I mean it was put in the game for people other than you but if it effects -you- then it has to stop! Yeah, nothing self-centered there.
And you still didn't explain what it is you have to do with flying that you need it so bad. If you actually did open world content you would of had 100 chests already just by tripping on your dick.
