90% of custom games are full of AI players making it impossible to get the achievement progression to actually count
And to top that off 90% of lobbies are last stand only or Arcade only or Team score only, We need a rotation of all game types and modes, This needs to be changed to either win 10 custom games of any type with 6 or more humans in the finishing photo booth or win 20 custom games 1 of each with 4 or more humans in the photo booth
Those are the 2 best options because getting 4 people in a custom is possible, getting 6 or more requires starting your own custom and hoping people join, and nobody does and if they do they just leave again as soon as they see you had to fill it with AIs to get it to 6/8 on the list so its at the top by default
Devs please do something about this, Its a good skin and almost nobody can complete it due to shit restrictions
