The vast majority of new players leaving FAF is a big deal. A lot of those new players leave because of people like you contributing to a more toxic noob-unfriendly atmosphere for them. Here is a link to a forum post on this very subject of new player retention with over 300 responses from numerous players in the ~3.5 months that it's been up: https://forum.faforever.com/topic/1100/why-would-you-have-left-faf/
If you actually want to better understand how the current system is not noob-friendly, you can read that forum to gain some perspective.
Adding a casual matchmaker option wouldn't remove the competitive matchmaker, and over time, the increased multiplayer player retention would actually increase the amount of people playing competitively as well.
To give you some perspective, something like half of all the games played on FAF are currently played against AI. There is a very large pool of potential players that can be integrated into FAF progressively over time. Creating a casual noob-friendly matchmaker option would help advance that process.
