2. Trolls
You are going to get people coming after you in GTA Online, that is a given and it is perfectly acceptable. But when you are killed by them, you want to have a fair chance at getting revenge. Constantly respawning awkwardly as they simply wait behind cover doesn't seem to be all that fair. When somebody targets you, they are endlessly killing you and getting in the way of you actually doing anything and draining money in hospital bills, playing GTA Online soon becomes a huge chore. A chore that makes you want to leave the game and go in a Freemode alone - And where is the fun in that? Most would say go into passive mode, but sometimes you want the feeling that you can adequately protect yourself from getting attacked and not have the impending doom feeling that a game mechanic will prevent you from doing so. A prime example is exiting a garage or house. If you go into a Garage and then come out, you can't see the map until you have got out - You can switch this setting but most players call Lester to make you think they have left the game as they wait outside for you to drive out. You may then have to endure a cutscene of you coming out slowly each time before you drive off. This gives an opponent time to set up a sticky bomb trap or blow your face off before you can even get a foot on the accelerator button. Then you repsawn close by without your car and have to endure the same process over and over again until you can finally get the upper hand, kill your troll, get in your car and drive off happy.
