Stop punishing "dodging"
Recently I felt like the most unlucky person in the world. Yes, I am very much aware someone playing badly is not trolling but hear me out. I had 6 trolls (dodged twice so experienced 4 in-game). The four wonderful individuals I had the pleasure of being on the same team as were as follows:
An adc who ragequit after dying 3 times (around 10 minutes into the game)
A bard support who went top levels 1-6 farming the toplaner's cs despite everyone telling him (first politely) to go to his lane. He ignored it and returned to ruin toplane at level 10 onwards
An Ashe jungler who farmed all of the toplaner's cs multiple times despite them politely asking him to stop. The Ashe even deliberately let the toplaner die so he got get the kills (and thus all the farm too)
A Miss Fortune Jungler who was last pick. Team chat spammed her of her correct position. She ignored it.
Dodging is not being toxic really. It is an act of heroism so that you don't have to deal with this. Why punish it?
