Premades who do stupid things for their own humour, please stop
I'm not talking about poor gameplay but rather just poor humour. Think about the poor players stuck with you on your team.
I got stuck with this premade in 3s who basically tried to troll me at the start. One of them said they were leaving and actually did for a few minutes while the other pretended to rage and inited a kill at the beginning(running under a tower with no minions or enemy in sight is initing, there's no other reason).
We actually won, but it wasn't enjoyable for me. I'm sure they were laughing their rear ends off but I just wasn't in the mood anymore.
