Diamond Supp main LF team or Diamond adc duo

As title says... looking for a team. I'm currently d5 and I main support. I've hit diamond every season since season 3 although I have taken numerous breaks along the journey.. I'm looking to get a bit more serious and am lookin for people to flex queue with and climb the rankings WHILE having fun. I can't stress that enough... I enjoy the game.. win or lose (though preferably winning). I'm not looking for a team that tilts after every game.
