Just adding feedback.
I feel the challenge system is still very frustrating and very disrespectful of players time.
Challenges where you have to win game types are fine, if you can choose the game type.
I have spent way too much time trying to get stronghold matches. Quitting the games is not an option because you ban people. Which feels like you punishing people for trying to complete the objectives you have set for them. ( I understand that there are challenge swaps and I have used them to get something I can enjoy doing.)
This makes the ability to gain xp random, which is not fun.
Challenge swaps feel like a sign that your system is broken in general if you need to give people the option to op-out (but only a limited number of times…).
Suggestions:
Please make the challenges doable with the game types available. If the desire is to not create a playlist for each game type then win specific game types should be removed. Replace it with something more generic like some of the newer challenges (accumulating game score but not specific to a game type).
Create playlists for the different game modes.
Second topic.
I would prefer to see slayer removed from the play queue since every other game type is slayer or some other queue of only objective type game modes.
