In terms of your idea on how to play the game in a way you think is best i’d say muting everyone is a step one. And look on the map. Whenever i queue up with a friend the guy tells me “the whole team is spam pinging you lol” And i’m not even noticing it since i’ve already pre-muted them all at second one. (With a 70+% winrate on shaco jungle, based on 300+ games.)
Perhaps if we start looking at roles for what they are and keep that in mind during the game we will all get along better.
For example, when there is no vision set up around an objective and we don’t know where the enemy is or if they’re cheesing in a bush i personally think the following:
Why did our support or mid/adc not at least put a ward at the pit. Ofcourse a jungler is also responsible for vision but most of the times you tend to leave one for your top laner (i do at least.)
Another one is, after objective is taken a lot of coin flip fights get started by the team that just got the objective and in most cases does not end in their favour. I have found that after the objective is taken it is best to boot out asap and keep up the tempo, which i still always do even though the other 4 team members are going bananas after the objective was taken already by us.
