Sadly they would be flooded with false reports.

Tonight on OCE theres one group of players who somehow ALWAYS end up in the same team, they are somehow coordinated and manage to wipe out people in an instant. one stuns, one pops its big shot and they consistently do it.
Why do i bring that up?
Its an example of what i experience in almost every match.
I play Dancer, im viewed as an easy kill.
The only thing my job is good for in PvP thanks to SE's stupid PvP job design, is making enemies waste their cooldowns on you so your team can HOPEFULLY (lets be real 99% or people you get matched with are too useless to take advantage) take advantage and clean them up.
My boards normally look like this: 0,8,5+.

Basically, people who play jobs that ALWAYS get focused down, or simply walked over due to bad balancing, would get mass reported for 'throwing' when they are likely trying their hardest despite being given a twig while everyone else has a a gun and riot shield.

There really does need to be a way to easily report obvious win traders and people throwing/afking etc, but sadly for people like me too stubborn to play Meta?
The system would be bloated with false reports.
