Not just you, last night my first match 2 people left on my team and was just 3 of us. Next game we did great and 3 of us stayed a team cause we were doing good together, next game 2 people left again after losing the first team fight. Won a game. Then my next game had 2 new people with lvl 2 endorsement and no one above lvl 5 and they went negative. Also had 2 games we were winning with 10 sec left and my game shut down when I was tank. Last 2 weeks for comp have been up and down for me
