This situation sucks for everyone really, all threats alike. The point was to allow the few remaining players (especially on NA) to be able to find opposition, I'm pretty sure they're aware that this won't bring any new players whatsoever. Now everyone needs to suck it up unfortunately, golds are frustrated because they get matched up against or with bronzes/silvers, and bronzes/silvers are frustrated because they get roflstomped by golds.
The best thing you can do now is try to find people to group up with and make the game a bit more enjoyable, and ignore the shit talking. Players will be toxic regardless of their threat level, this is an online game, don't expect people to be respectful lmao.
