@DoYaSeeMe those are the normal ways to die, from a 3rd party, against a full squad (In squad mode, ofc.), or against one player, and there is no way you can blame anyone except when a cheater got you.
If you are not a fan of this mode then i can understand why teamming-up is not a problem for you. 2 or more players literally at the same house rotating waiting for you. Solo is not an ideal environment for having teammates on your back, how is that fair? And if you said that solo mode is actually a 1v59, have you ever see those 59 players running side-by-side shooting at you?
There's proofs that people intentionally trying to be in the same lobby so they can team-up. The simple question is, if you want to team-up, why don't you do it in a normal queue? And the answer is of course, because it's easier to win if you have teammates while everybody else is on their own in solo. And that leads more player to join the train and taking an advantage and solo mode lost its purpose.
If you play PU*G, there is a report button for teamming-up, even when you are in a full squad mode, the feature still exist.
The tourney sounds promising, but that is for another matter, let solo be solo, don't ruin it because you have the "strategy" that obviously unfair to others.
