What do people like you wanna hear? That Blizzard is personally coming to their houses and puts a gun to their heads?
The only choice these people can make is whether they want to compete in the world first race or not, whether they want to raid mythic to begin with or not.
If they make the choice to raid mythic, or try and go for world firsts, there are things they have to do. Period.
You can't say you wanna raid mythic and join a mythic raiding guild and then say "yeah but that artifact power thing, fuck that man, I'm just gonna wait til I have artifact knowledge level 25, then do a couple of quests, bring my weapon up to 35 and that's it for me"... while everybody else is busting their balls trying to achieve their goal. They're gonna sit you down and tell you "look, you're not taking this seriously enough, and you are only weighing us down, everybody else is doing everything they can, and you fuck it up cause you don't give a shit, you have to go".
There is no way to casually become the best.
