LoL game mechanics cause the toxicity (Score 1)

I really think the toxic community is produced by the game mechanics. The whole notion of a hero that can 'carry' the team coupled with the fact that a player death feeds the strength of said hero makes dying really problematic. The carry hero is going to grow too strong to defeat after a few kills thus making the game bitter for the losing side. As a result, its your own teammates that berate and thrash you, not the opposing team. I do feel like Blizzard's latest rendition of this MOBA model (Heroes of the Storm) has took a step in the right direction to prevent the toxicity by changing the penalty of death and dramatically reducing the strength of a 'carry hero',
