You might be a new player to aoe4 and not know yet how the matchmaking works.
Matchmaking is based on ELO, for all queues. 1v1,2v2,3v3 and 4v4.
Your rank in this game means basically nothing, what counts is the elo for the system.
Someone who has not played 3v3 yet but is very experienced in 2v2 and/or 4v4, will basically have a trash elo in 3v3 and can be shown a conqueror.
Now when he starts a 3v3 queue, he’ll get matched with people who are in his elo range.
This player basically is a noob on paper regarding 3v3, but a good player in 2v2 and/or 4v4.
Once he plays a few matches in 3v3, his elo will eventually change towards his actual skill-level.
On top of that, the new season just started and everyone got a rank-reset.
The actual rank of most players is VERY off still.
Give it a few days/weeks and people will settle in their right rank.
Right now an unranked player could be a conq3.
It’s just how it is.
On the good side, if you play vs these good people, you don’t lose rank points when you face a defeat and gain massive points when you win.
So it’s time to be brave for you, go through it and learn how to beat these players by playing against them and watching your replays.
I recommend playing more 2v2 than 3v3 and 4v4, as you learn faster how to be a good player in there.
Personally, I started playing 2v2 before 1v1 and my friend and me very quickly got to conqueror, a few days later conqueror 2, then almost conqueror 3.
After that I started playing 3v3/4v4 with other friends and it felt very very easy, because these big games are generally of lower invidivual skill and it’s very easy to get a high rank there.
People you face in 2v2 who are conq1+ ELO (!) are often hard to crack. In 3v3/4v4 not so much.
In 1v1 it’s obviously even harder, regarding micro, mechanics, multitasking and so on.
You could also play more 1v1 to up your game, there you learn all the tricks, mechanics and builds quickly and can then transition them into team-mates.
