Norms - First and Last to connect
I've connected last most of the time because I'm playing from Korea to NA servers. One thing I'm very frustrated about is people calling false claims that they've gotten their lane because they connected first and dish out your call cause of it. Came across a few people auto-locking, while I just picked my Champion and had others even confirm that I got the lane.
The worst thing is getting reported for things you didn't even do. Ex. - Doing bad at a game because you had the person be a parasite at your lane and get reported.
I really want Riot to change this 'system' of having joining a queue and shows the players connecting #1-5 first and last, mainly because of people getting toxic and abusing it.
