With crossplay, matchmaking will be tighter and solos won't play 5 stacks right?

The limited playerbases forced Sloclap to have extremely loose matchmaking to get low queue times, but now that all the platform playerbases will be combined now there won't be queue time issues so we won't need to suffer 5 solo vs premade stomps and low quality wide skill difference matches right?

Because what the point of implementing the solution if you're going to keep the undesired temporary fixes?

I'm not missing something am I?
