I know this suggestion is a year old, but (as with many other older suggestions) I am on my knees, begging.
With the anniversary preview of what is to come, I realise that once the level cap is increased, getting the achievement for winning rounds were the enemy is above the current level cap will only become harder and harder to get. Not because it becomes harder to defeat, but because it takes such a ridiculous amount of time to even get there with the timer.
Please just remove it. It is such a flow-disturber and all in all makes the gauntlet anything but fut. It is just something I do sometimes because the quest shows up. But I never voluntarily think: oh let's do some gauntlet.
