I think you have to look at it this way...
Achievements mean absolutely nothing in terms of Player Skills and Capabilities, Cool... you have played enough Warzones to get the Manhunter Achievement, but you can still very well be crap at the game, I have seen plenty of people with more than 2 Valor 100 Characters and still be absolutely terrible at the game, Just because you have played something for longer doesn't mean you have the same learning curve as someone who can literally adapt to a class very quickly and learn all the fundamentals of PvP, I have seen it happen before and to this day they are insane in Ranked with more than a 70% Winrate, they even became better than me within a few months and I have played Ranked since season 2 and had Gold a few times.
How I see it is that you want people with not as many achievements as you to be in a much more less prioritized queue, that my friend... is just unfair. The game isn't gonna change something as petty as this and this is not a topic with "Considerable Gravity" The match making is fine in Ranked, the best the game developers can make it- Regular Warzones are fine aswell, why should they do something to change it? It is Regs for a reason, there is no stake on the line such as your rating, you go in and you improve yourself, even if the system has played against you.
I don't want to seem as coming across harsh in your statement... I am just trying to prove a point.
Have fun in your endevours in PvP
