Connection issues. I can't tell you how many times I sniped someone and didn't get a hit report in crucible while going for my thorn bounty. All pvp games struggle here but destiny really is bad. I think part of the issue is that they actually do a good job of smoothing the game out so it doesn't feel choppy when you lag and there are no connection error bars to tell you when it's acting up. I know CoD would skip players around when there is lag but I hardly see that here.
