The 1017ocaust kept me from progressing steadily through the main quest, setting me back 300 mythology tokens.
If people right now aren't rushing to endgame because that's what they ordinarily do in MMOs, then I'd will wager it is because they don't want to "lose" any more mythos. Whether you beat the MQ, the timer is running and you can't stockpile mythos allowances like leves or anything like that.
