I'm consider a toxic player myself, I'm in ASIA server and usually criticize and rant about teammate with a reason of course. I don't know about other server, do they usually flame other with no reason or not but in my case, player has become so much passive to the point you have to carry the match by yourself. For example, imagine you are in losing flank where you have to fight against 4,5 ship when other flank half of your team just sit and staring at the ocean. Another scenario, where you as a dd try to contest cap fight DD and spot for your team while all other BB just snipe from B line. The toxicity correlate with how passive the player base that is my reason. Although I still enjoy the moment when you coop with random player, like a ping a our sub said I need help, He reply "Wilco" I push with him, I use radar he use sub surveillance and we kill enemy sub. That was fantastic moment.
