Rude 4 Man Pre-made.

My last game was my first experience with a toxic four man pre-made. Most of the pre-made teams I have encountered have been super nice and respectful, but not this one :/

I was playing blind and I went to play a quick match. I really wanted to practice with Janna (I'm a support main) and then call it quits for the day.

When I finally get a game, I am the first to enter the room. I am the first to call, I quickly call support, and wait for the rest of the team to call and choose champs so I can see if the comp would be good for Janna.

The next second, I notice they're all a premade. That doesn't discourage me though, as all of the premades I've met have been nice people and understanding. However, when someone on our team insta locks Braum, I get worried. I type that I called support first, but their team gives me bs excuses along the lines of 'he has super fast internet and got in the room before you and called' even though he entered the room after me.

'BS' I type in chat but I'm willing to play other roles and know that this will get nowhere if I don't.

I tell them I can ADC, mid, or top. I believe I was super flexible in the sense that I was willing to go other places but still they tell me 'no'

'You're jg' they say in chat. I've never jungled before, not even once. I have no clue how to jungle and would be a hinderance to the team.

I tell them this in the hopes they'll listen. They don't. I ask if I can duo top then, (which I hate doing) and the Garen tells me 'stay out of my lane bitch.'

I had 10 seconds left to pick a champ. I decided I would go top anyway. I'd be less of a hinderance in the game than if constantly got executed. I didn't want to dodge. I was so angry that I couldn't even find Poppy in my champ pool. Thinking, wth this is gonna be terrible anyway, I just click on Heimerdinger and be done with it.

After that they all start to insult me and my champ choice. I ignore them.

When we get in game, I discover that the only person with any mental capacity on our team is our Veigar. He took smite at the last second. He told me to go mid and that he'd attempt to jungle.

'This is your fault if I feed' he says.

He actually did pretty well for his position. He went 2/2. He also refused to gank my lane at all. I discovered that the enemy midlane teemo was pretty bad, and tell Veigar that it's an easy gank. Doesn't gank my lane. At one point I was overextended and got ganked and died. In all chat, our Braum puts in quotes "teemo's bad"

I then tell him that I got ganked, and he said 'oh' great map awareness for a support -.-

We ended up winning in the end because our Lucian carried and they surrendered, but man I'm sure if we lost I would have had to take loads of insults from them. I reported them at the end.

Any of you had similar experiences and know how to deal with them?
