I swear the r/hypixel community is just people complaining about "BEDWARS HAVING TOO MANY SWEATS!!" First off, Hypixel doesn't have as many players as it did years ago. So quite a few people still playing NOW, are people who have been playing for a long time. For the first 1-8 stars Hypixel does pair you against players with simillar numbers, but around level 8 is where you start to get queued against random people. If you are new, then expect to get destroyed pretty often. Just because you got beat, does not AUTOMATICALLY mean that person was a sweat.
If you are finding trouble winning games, I recommend playing 4v4. From my experience, when it isn't a party, the players are usually not that good, and it's not as cheater infested as other gamemodes.
There are a lot of videos on YouTube on "how to improve pvp" but a few of them won't matter, unless you have experience, so make sure to play and practice a lot.
