I’m sure these are now just here to waste challenge swaps. And what’s ironic is still after swapping you’ll be given a different challenge but in the same mode, I’ve experienced this with Land grab multiple times (almost like the algorithm knows what mode the player doesn’t like). To make this matter worse depending on your location/time you might not even be able to find a match at all. Say what you like about Fortnite but they know how to design and implement their challenges. I’m pretty sure mcc doesn’t even do this to that degree, with mode specific being more present in the seasonal challenges.
It’s honestly frustrating especially during the current state of the game. If you want more players to purchase the battlepass design it so the challenges are fun aswell as…. Challenging.
