One of my favorite things to do is complete challenges and unlock xbox achievements for games. Destiny is the single most broken game i have ever played when it comes to challenges and achievements. These are only the achievements I KNOW i have completed: witch hunt warlocks killed: 1744 hunter killer hunters killed: 1565 giant killer titans killed: 1440 Ask questions later first blood medals: 17 Notorious crucible marks 300. 100 per week 3 separate times strenght of the pack complete a strike with three clan members 3 times excessive force heavy weapon kills :117 crucible heavy weapons kills And this doesn't include the grimoire cards that are not unlocking. Between this and all the connection problems and glitches I can't comprehend shelling out $35 for the dlc's if its all going to be broken and buggy. Some bugs okay, but this is ridiculous Bungie, please man, fix this junk.
