New Kabam employee
First, let me say thank you to Kabam for doing something they should've done long ago and hired an employee who has the primary responsibility of focusing on minimizing the cheating in this game.
I have but two minor suggestions on this topic. First, I strongly believe for them to be good at this job, they have to understand how this game works, preferably be a seasoned player.
There have been several times where I've filed a ticket against a player with 100% abyss profile pic but still has 4*s in roster and it was clear that the person handling the ticket had absolutely no clue why that was an issue. Point being a little bit of common sense combined with game knowledge will make them much more effective at their job.
Second request might be a little trickier, I believe they will be more effective at their job if they have access to community concerns. If would need to be a fair way (to avoid getting swamped in irrelevant allegations by someone who is just mad they lost in BG) and would need to be done in a way where players aren't publicly blasting other players.
It could be as simple as setting up a process (and telling the community) that allows allegations with proof to be sent directly to them. However, most of the proof the community can send is screenshots which means nothing to them if they don't have some basic game knowledge (such as why a 4* Groot shouldn't beat a r3 6* penni in under 8 seconds in BG).
