I don't think anyone wants that. But to be a mythic raider requires a time investment that is insane. Besides actually killing the bosses, you are researching your class constantly. If you are a guild leader, you are constantly recruiting new talent that can pour tons of hours into wow and constantly weighing if you should either keep the guild going, merge with anther guild, or gquit and join another mythic raiding guild. If you are not a guild leader, you are constantly weighing if you should stay in your current guild or gquit to another guild. You got to do things like run specific m+ dungeons like 25-30x just for one BiS item.
The bottom line is that the "competitive players" have oceans of free time to do all this.
