Some are just ridiculous. Especially the online ones. For players who don't like the online pvp, it basically forces you to play crucible. Get 500 void damage points. 5 per kill and 2 loss for each death. It's to much of a challenge. Either reduce the amount needed or increase the points given. Yeh there will people saying well don't do the challenges then. Well -blam!- you who think that.
