You can't call for other people, let alone 4 people.
I just played a game where I joined, I called mid, but someone before me said "I'm top, ... is jg, ... is adc, ... is mid" (they're in a party), then they were like "Sorry Diana ur supporting"
Seriously, it bugs the hell out of me. Calling for someone else is bad enough, calling spots for 4 people including yourself is trash and disrespectful.
I mean w.e it's not a big problem, I dodged. Just shows how trash the community is. Fix your game riot
