But isn't that what mythic is? How lesser of rewards are going to make people do an non timed over a failed timed run? After all the same people asking for the timer to be removed claim no one wants to do a failed time run in a pug to begin with. If most people do not want to choose to do it with out a time limit why doing it with lesser rewards make more people want to do it?
Look at how Mythic rewards 430 item level. With +15 465. In order to offer less rewards with a non timed run they would need to significantly lower Mythic 0 or significantly raise Mythic+. Which means they would need to also raise raiding gear and the other equivalent level rewards. Which means there is little reward for little extra challenge. As unlimited time to kill things is not that challenging. Which is why the Mythic+ runs are timed to begin with.
It isn't counter intuitive that more time can lower value. If a person runs a mile in 10 days versus the same person running it in 10 mins what is a bigger accomplishment?
