Okay, so I'm getting really sick of the same stupid challenges. Get 100 kills in firefight, get certain amount of kills with pistol, win 5 games, let's see something big! Sometimes the challenges are so hard, and you get like only a thousand credits, psh, let's see some daily challenges that you can get 5000 credits plus on each, shoot em at me, I'm tired of these wimpy challenges, and of seeing the same ones, for low credits. Don't even get me started on weekly ones, who the he'll can beat a campaign mission with legendary on and all skulls? It's really hard, and not worth it for the credits they give you, step up your game Bungie.
