Passive aggressive trolling.
This is literally the worst type of troll. That kid that picks MF mid, tank Shaco top, Heimer jg, etc. and swears he does it all the time and it's good. Yet he/she knows that they're just trolling to piss off the entire team and so they'll say super positive things to try and make it look like they're actually trying to win and so they can't be reported. This is the absolute worst type of player to have on your team and I'm so fucking tired of getting trolled by these passive aggressive A-holes. Your report will do nothing because those players continually say really positive things like "come on guys we can still win" even though they're 0/10 and basically running it down mid every time they see the enemy team. If you say ANYTHING they're the first to go into all-chat to play the victim about how toxic their teammates are. My god this community has gone down the shitter when this type of play is entertaining to people.
