As the title says. There is always someone in your team that is having a bad day and not performing well. Trolling those people is always fun right? Here are a few to confuse your toxic team mates!
1. Keep a cool head so that you can make proper decisions!
2. Compliment him if he does something well and dont talk about his fails
3. Try to help his/her lane
4. If he stats flaming be really polite and positiv, that makes his rage very akward
5. Try to shot call and coordinate something with him (like I am roaming to your lane soon, dont shove etc)
6. If his team mates start blaming him, try to calm down the situation
Hope you have a nice day
