Also, not everyone runs with only a specific comp for mythic+. Only the crazy hardcore tryhards, or retards do. Most go with adequately geared people that don't die to dumb shit.
At higher levels, you begin to use the utility of classes more often, and learn when to use the optimally, to mitigate damage and ensure success. So the timer is present, but how you manage to beat the timer is your measure of skill. Whether its by being more defensive at some points, or knowing when to know to go full retard, etc.
