Re: what to do when team is trolling?
The only real solution is to play with premades. You can never assume that a random teammate will think exactly the way you do in every situation that you may encounter in this game. In my experience, most times when people say "my teammate is trolling me in ranked" is more likely because you dont understand each other or have a very incompatible playing style. It will ofc feel like you are being trolled if you crack two enemies inside a building, you push in, knocks two of them but dies to the third just to realize that both your teammates ran the other direction. But I promise that its not them who deliberately are trolling you; its just the miscommunication/misunderstandings that comes with playing with randoms.
For instance; the example you mentioned about "teams that dont ress you on purpose".. I have played at least one account from Gold 2 to Diamond4 totally solo with two randoms every split since S3 or something and the total number of situations when randoms just refuse to respawn or revive me just to troll me can be counted on my 10 fingers.. It just doenst happen that often.
But there is a huge difference between trolling you and just not prioritizing a res on you. And based on the countless situations when a random start to scream "RES ME RES ME" right in the middle of the fights make me pretty certain that people just dont understand when you should and should not go for a res. Same goes for Respawns. No way I would demand that my teammates MUST respawn me if its 10 squads alive in round 3...
