Poor matchmaking has been an issue at least since Year 3. Even with crossplay, poor matchups where there is a significant disparity in reps, skill, experience, game sense, or a combination of these still occur.
If For Honor wants to be a competitive fighter, that encourages good & competitive play which makes players improve over time, matchmaking needs to be a lot better.
See my matchmaking diary which spans over 6 months.

Below is a quote from one of my previous posts about the issue.
FIX THE MATCHMAKING
WHY?
Low reps & high reps players, and various skill types are mixed too often
This is not a good experience for anyone and is also a common complaint. While some veterans and higher-level players may enjoy the easy wins, poor quality matchmaking doesn't encourage good or competitive play for the competitive fighter For Honor wants to be.
Rep doesn't equal skill but it does equal experience
The veterans are more likely to have a better understanding of the game modes, and a better grasp of the game's mechanics over a greater range of heroes and, thus, have an advantage over the newer players who are learning the game and lack the knowledge and muscle memory veterans would have.
The opposite also happens when the veteran is expected to carry a team of rookies in an objective-based game mode. As a result, veterans lose for the wrong reasons and are left frustrated.
Reduce unnecessary reporting of players
Poor matchmaking can also lead players reporting each other unnecessarily. Typically, a veteran would be tempted to report a newer player for 'griefing' for not doing the objectives, though not fulfilling objectives is common for new players as they are still learning. As a veteran, I've been in this position many times.
From the other perspective, a newer player may be tempted to accuse and report veterans for cheating as they may seem flawless in both their offense and defense. I see this a lot in the in-game chat.
Reduce the complaints
Not only better matchmaking bring a much need quality of life change for both veterans and newer players, but this would also help reduce the cries for nerfs for new heroes and reworks where, again, the veterans would have an easier time making the transition and take advantage of the newer players as a result.
