Pretty much a terrible idea, and this is coming from a friendly player who shoots as a last resort (unfortunately "last resorts" are very often the only kind of resort in the game). I don`t want my encounters to feel safe, if i have a gun, i`ll use that leverage by saying to the person that if they do not comply to what i say i will shoot. You have to be strict and not seem like some naive guy whos just asking for it. Generally, as you play more, and decide you wanna try to team up with a random, you can sometimes tell if someone is going to backstab you or not. As a general rule however, never team up with a random if you value your life, and also if you have anger issues, some of the traps the "pro" bandit set up include gaining your trust over several hours. Indicators that can show if its worthwhile to team up are: how much are they talking to you? what are they talking to you about? in which manner are they speaking (do they seem tense, relaxed)? do they frequently ask you to do things that will expose you? do they seem impatient to get somewhere? do they say "wait" alot? (possibly trying to get a friend over to shoot you over TS.) Hard to explain, but it can save you from the more amateur killers or just general trolls who think you are stupid. Generally if you are able to strike up a friendly conversation, then theres less of a chance theyll kill you, there are alot of exceptions though, again. I dont reccomend befriending a random under any circumstances if you have high-end gear. Go and join a clan if you want more reliable teammate, or ask someone from RL to join you.. By making this aspect of the game too "arcadey" it wouldnt be the great game it is, where you constantly have to think and take life and death choices at a moments notice. If you want to play MMOs where teamwork is integral there are several.
