thats not refusing to communicate. Thats intentional feeding.
it also depends on what you were doing. If you were trying to ward, but have bad map awareness, and get caught out, fair game. You just need to improve on your map awareness.
If you are running into lane, trying to shove a lane without vision and enemy collapses, fair game. work on awareness once again.
If you are chasing the enemy without vision and die. Fair game, work on awareness.
There is a line between intentional feeding and just being unskilled. Map awareness is a thing that needs to be learnt and practiced. Tunnel vision does make up for alot of that.
I very very very rarely report someone for intentional feeding. Yes its fustrating to see things coming and others don't see it, you expect them to be better at certain things. That being said, sucking is not something I'd punish someone for.
If they want to learn, fair game, I can teach. If they aren't willing to learn, I probably won't see them ever again, so who cares.
EDIT2: if they were just running around, standing there and literally not doing anything, not counter jungling, but just running into the enemy but dying. Then yes, I would report them under intentional feeding. Also keep in mind that he's a walking ward.
point is, I don't need refusing to communicate as an option (based on your examples), intentional feeding is enough.
EDIT: As for running around not doing anything, I'll give you an example.
Mid game is here; My team pings for dragon (both teams have 1 drag). there is a giant wave crashing into our top lane and I decide to get that farm instead as I believed drag2 is not worth contesting over for our comp.
They ping me to back from top and help them drag, I ping back to them to back away from drag and I'm on the way top. They spot the enemy team, get collapsed on and die.
Of course they blame me for not being there. But what is the right call? Keep in mind its a bronze game, and needless to say we lost that game. I think that probably in higher ELO play they would have better macro decision making, but in bronze, everyone just wants to fight all the time.
Eitherway, was I intentional feeding? Far from it. Was I refusing to communicate? No, I just didn't like their calls. Was I not doing anything? No, I was just doing something else the team didn't agree on.
Can you report me for unskilled if the option was still there? Maybe. But was the right call to get drag? or to get the farm?
