Instead of an [amount] and [time limit] Challenge just change the challenge to the following
Kill 50 enemies by pushing them off a ledge using psykenetic blast.
This way the player if they don’t complete the challenge in one go they’re not frustracted and feel like they’re making progress in little steps. I think people would agree that this is preferable to game after game of failed attempts. Right now grinding this pennance just sucks all the fun out of this game that i’m quite excited to fully release.
It doesn’t have to be 50 enemies but it feel like it would be a reasonable amount that you could focus on for a while and feel like your time isn’t being wasted. The current challenge discourages playing the game naturally and is just flat not fun. If you are lucky and find a game of randoms who want to grind cliffhanger it can turn frustrating for everyone if only one of them do the pennance after 15 minutes of waiting for a few hoards.
