It’s similar to the mission system of QW afaik most players don’t use it slow down the gameplay when you need to select a mission before you perform the selected task.
I watched the Container City video and made a screenshot of what I mean:

I don’t know if it’s possible but isn’t it better to “detect” what you are doing and give XP for it?
So you don’t have to select tasks in the middle of the game.
Or make it easier to select missions by pointing and pressing a key while you playing.
