The jolly holiday quest is extremely hard, even though the reward for it is an exotic (the chaperone) I found it extremely challenging considering that the last word has been nerfed. Also the quest description said nothing about deaths in the crucible taking away progess... so not only do you have to get 100 kills in the crucible with a nerfed last word but you also have to do so while every death takes away a kill from your progress (1 kill = 1%) the quest progress also glitches quite a bit and often takes away more than 1% of progress per death and sometimes doesn't give you progress for kills... in conclusion this quest is absolutely the dumbest and most unbelievably impossible thing to do in destiny!!!
