You should piss off enemy team and sugar talk your team mates
I think that getting inside your opponents head should be a strategy. We all know that when you get angry and rage/flame, your performance drops and you can spread it to your teammates causing all of your team to rage and increase your chances of defeat. This has been proven by all of the studies done by RITO and can be tracked by gold, click on the link where RITO proves this. So why can we cause the other team to spiral into rage while sugar talking our team? Why isnt this a major strategy that is talked about?
I.E. constantly spam taunt, laugh while your opponent is 1 hit away from death and let him live until you decide when he dies, get a kill in your lane and drop disrespect, when ever you get a kill all chat to the enemy team report "their teammate for feeding unskilled", say sorry for "their teammate", or just talk smack to your opponent all game, when enemy team all chats 'report X' ask them about it and tell them yes you will report that person, encourage the enemy team to fight with each other, when every possible add fuel to the fire (enemy team's), make jokes on their behalf (do you tan? A. cause you look pretty bronze), kill dc's, and all chat them a Q before ganks so that they are distracted and typing. etc.
Their loss is YOUR GAIN. The more THEY fight and get pissed the more their defeat chance rises and the more YOUR VICTORY chance INCREASES. look at the link for proof at what happens to teams that fight and rage at each other, if you are lucky they might intentionally feed or grief their own teammates or afk, 5v4s are your wins
That being said, im not saying you should cuss at them or wish them cancer, best way to get them to act like 5 year olds is to insult them like 5year olds.
On the flip side, be very very nice to your team, pretend your mum is in the room and she is making sure you all play nice. open up with a joke to boost your teams moral, communicate well with team and say GJ often and compliment them, make them feel they have a big pee-pee idc just what ever it takes for your team to be happy. TL;DR If you can piss off the enemy team your WIN% chance increases If you can promote team work and a positive attitude for your team, your WIN% chance increases
What do you guys think about this strategy? P.S. to counter this strategy JUST TURN OFF ALL CHAT!
