Not sure if sarcastic or not, but I will take as a legit comment.
1.) Playing Leona, so there is not much complexity revolving around that champ that needs to be mastered in order to play effectively.
2.) The decisions in question were things like choosing to back instead of staying in lane when I was at 15% or less health and there is an enemy talon missing from mid lane. Apparently the correct choice is to stay in lane and wait to die.
3.) The other time the jungler was bitching because apparently, as Leona with a Jhin adc, I am supposed to go balls deep into the enemy bot lane at level two. Just fucking dive them without any set-up and hope that Jhin is able to output enough damage to get a kill or two. That is what Ivern told me to do. That Jhin should already have 3 kills by now (pre level 6). Instead of constantly diving in, I decided to sit back and essentially glue myself to my adc to protect him since he doesn't have much self-peel. Protecting your adc is apparently frowned upon.
4.) Am I a fantastic League player? I wouldn't be in Bronze if I was. But the rest of this team is in Bronze too so you should just suck it up and understand that we are not going to make fantastic plays. It wasn't as if I was trolling, or missing all of my abilities, or diving at the wrong times, or building wrong, I just wasn't a platinum player and Ivern was so aggressively toxic that it literally made it difficult to concentrate on the game.
