Very, VERY sorry I could only like that once.
"This is a BR, not team deathmatch." Six years in and I still daily play with randoms who simply do not understand that there is any difference at all.
"I don't understand the logic behind solo queueing and then expecting "stacked" results." Another piece of wisdom which is so obvious to you and me, but which is completely lost on most players. They assume that every player in the game has watched all the same streamers and understand the META to the last detail. Even though the streamers are so often wrong it's almost laughable.
Great post. Nothing irritates me more than people who solo queue and expect everything to just fall into place. I solo queue and I expect absolutely nothing. And I'm never disappointed.
