League of legends is not Multiplayer Fun, but rather a psychology session.
What do these players want? Why are they behaving like that? Could it be the cause of an accident in their younger years? How far can i go with lecturing them to avoid them flipping out? What approach should i have? Should i give off the "i don't even care about what you do" vibe to apply reverse psychology, or just straight up tell him to shut up and play?
In the past 3 years i've seen a lot of people and based off just a couple of chat logs, i can presume what approach would be the most effective. If they make a mistake, should i encourage them to cause more positivity in the team, or tell them what they did wrong so they can improve on that, and not necessarily go on tilt just because i pointed out a mistake?
Of course i behave towards them as their partner and their teammate, but in game i just try to figure out what is the best for the team, and what mindset could get us, not just me, all five of us closer to victory. It's really interesting if you try it out because the usual soloq struggle will become much more interesting, a sort of an experiment of peoples behaviour.
