Actually, the OP only gives proof for one game. I’m not sure that’s enough proof to substantiate his claim here:
He hasn’t proved that this is happening to a “hundred players.” He hasn’t proved that 50% of his matches are against 2200+ players. And he hasn’t proved that people are doing this for gold. I’m not sure if the gold part is even relevant tbh, as it’s completely protected under the ToS. So yeah, it’s hard to really grasp how much of a problem this actually is.
Admittedly, these claims are hard to prove with evidence, especially the gold part. They would either require a statistical analysis and data reconfiguration that adheres to proper protocol and methodology or internal data from Blizzard themselves.
The OP’s arguement here seems bold, but it’s worth noting that Blizzard actually has a planned fix for this.
Which should help reduce the likeliness of running into higher ranked players.
