3 Stack Tryhards in Pubs

A higher portion of the playerbase are casual players and a majoriy of them don't play ranked or haven't even left bronze.  Do you think they like facing 3 stacks of diamond and above tryhards in pubs?  No, that is why so many people complain about pubs being too sweaty.  If they wanted to play that way, they would just play ranked.  Actually, ranked might be easier for most people who don't have a 3 stack because they would be in lower tiers.  It's just not good for the game for casual players to have to be in lobbies like this.  I solo q and a lot of times my teammates are lower level and not that good, then we get sweated on by 3 stacks of diamond plus players.  Do you think these teammates of mine are having fun?  Probably not.  I can hold my own but when I have to face all 3 of these players after my team dies and they're still sweating on me, even tho I'm the only person alive, is just lame.   I get it, some of these people want to stroke their egos by going into pubs and destroying casual players, good for them.  My issue is, Respawn needs to do a better job with matchmaking.
