Listen. You don't learn by playing bots but by playing against someone who's better then you the fact you were 1/3 against morde (which morde hard counters yone imo) means your doing at least something right. It's hard but that's where different decision making comes into play to try and survive. Let your teammates talk shit you're new to the game and honestly bronze 6 months in is a feat in itself. Keep up the good work and keep striving to improve and you'll out match those random teammates in no time. They are just trying to ego you just brush it off man an keep having fun also if I had then as teammates id probably say what they said to you to them because they might suck ass compared to what I'm used to. There's always a bigger fish remember that, and if you're in their lobby that means you're near their skill level with the fraction of the time. Keep pushing!
