#1 Getting stuck on little objects while jumping and backing up!!! SO ANNOYING, especially when it's a pivotal kill in the match. Like the enemy team is capping B, you know it's going to be a Breaker if you can just bust out your Nova Bomb in time, you're gonna make it! But then a 4 inch rock makes your jump have 50% forward momentum and you don't clear the wall, and they cap B and spread out. Commence screaming. #2 Lag. Other players not taking the appropriate damage, or seeming to kill me around corners, and the infamous: I go to shoot someone, raise my gun, pull the trigger, and then my gun kicks out of ADS. #3 SLAUGHTER RULES. I have learned that a lot of people don't even realize this is happening, but if a team fails to score 65% of the other teams points, the entire lobby is kicked back to matchmaking. Nothing makes my blood boil more than Destiny giving me crappy team mates, or me having a really bad game, and then being unable to get my revenge. (except for #1 and #2 which can sometimes cause #3) #4 Team mates not picking up the heavy!!! I wrote a whole post on this. #5 Team mates eating rockets with the back of their heads. Not their fault,but grrrrrr.
