Overwatch Toxicity

I love this game so much but recently it's become a burden to play Comp with the amount of toxic players that dont want to cooperate with anyone from throwing games to picking 4 to 5 dps thinking ita viable (aka never works). I feel as though im wasting my time even playing it an eventually im just going to stop all together which is such a shame but unless something is done im just going to hang it up :/
