Believe it or not, @bouncingbrick , you're not the first person to make a post like this. As @daalnnii said, it is in place to make the terrible matchmaking this game has ever so slightly less terrible. What do you really have to gain through reaching rank 50? A meaningless badge that lasts only the duration of the next season? A couple of extra packs? There are better ways to get em.
If this is your first time attempting to reach Ultimate, then I understand the eagerness to get there. It's somewhat of a self-achievement. If you are unable to reach it, you shouldn't be aiming for it just yet. If you have reached it in the past, then you will know just how little difference it makes in the grand scheme of things.
