"Teammates" - Once Again

I agree with @E9ine_AC . Teammates will usually suck and only on rare occasions will you randomly be matched with random players who just happen to share the same strategical views and play style as you (too many blame teammates for being bad only because they dont play the game exactly as you see it in your head, which ofc is a ridiculous and immature way of looking at it).

The only you can do when playing with randoms (which I do at least 50% of my games) is to first and foremost mind your own business, play in way that maximizes your personal benefits, which in some cases IS to play as a team, for instance when you notice that your teammate is good etc etc. 

And lets be honest here; the reason why you can land 4k bomb games IS because

1) your teammates suck

2) many of the enemy players suck as much as your teammates.

Whenever you go 1v3 and solo wipes an entire team, one clipping every member of that team is possible because those players suck =) No way I would have got 4k dmg in that game for instance if my teammates had been good OR if my too many of my opponents had been good...  I spend the entire game reviving and respawning them and even though they made very little dmg, they contributed by soaking up enemy dmg.
