Basically you go to hero gallery and you set perks as “favorite” and then the game will just auto-select them when you reach the required level. This happens so many times when in the middle of a teamifight I pick the wrong perk, or if I hold my shield up and press the perk button it will count towards it as well.
That defeats the intended purpose of perks. I know we aren’t there yet, but the idea is that depending on the circumstances, you select the peel for the situation you are currently facing. Some do it better than others.
Essentially, load outs would force them to admit they failed. It’s never happening.
