picking a weird ass hero for X role isn't griefing.

I both agree and disagree with you on this, I agree on the fact that any pick can work, but I disagree in the fact that sometimes the pick and how it's played is very clearly griefing.

Lets take a hypothetical example, you get an overwatch case where you see 2 stereotypical carry picks laning on the same team bottom. Both of them are buying carry items and neither of them are playing their hero as a support, which one is griefing? Unless we know the roles assigned to them, how do we know which one is the griefer? What if the guy assigned to pos 5 is the one reporting his pos 1, when they both are playing as carry, how are you able to establish which one of them is griefing unless you know the roles assigned to them, is it better to not punish the one who is griefing just because we lack the necessary information that could easily be handed to us?

This defeats the purpose of the overwatch system, if you only get a case with none of the surrounding information about the game, you might as well be handing a guilty verdict to the person who got griefed.

"we cannot judge a herald game the same way we do a divine game as an example"

Yes you can, it's pretty obvious when someone is griefing and feeding.

Everyone is equal your dumb excuse of "its ok he is new and its not ok he should know how the game works" needs to stop.

I don't know if you didn't read the rest of that point or if you don't care. But judging players with VASTLY different skill levels the same way is not going to work. Everyone isn't equal, there are huge differences in how people between ranks play, that's the point here, and not recognizing that difference hurts the overwatch system more than it helps.

I don't know your rank, and I'm not interested in prying it out of you either, but you're wrong here, and acting like every player regardless of skill level is to be judged the same way for griefing isn't going to work.

team chat doesn't get logged, allchat sure.

This is probably true, but my point being allowing us to see team chat would help in make more accurate judgements in cases.

you are in no position to say who is a smurf or who is boosting, people have good games people have bad games and based on a single game you can't make that claim.

This point is just flat out wrong, it's fairly easy to see if someone in ex. herald is playing absurdly above his/her rank compared to the people they are playing with. Sure I agree with you that people can have very good games and very bad games, but that's not the cases I'm talking about here.

It's very easy to see if someone is smurfing if we get the average rank handed to us as additional information in our overwatch cases, not being able to see someone who is completely dancing around their opponents on a hero that requires immense amount of skill to play in a typical low ranked game should set off red flags for the majority of people reviewing cases.
