Making Abyssal depths rare but more rewarding?

So the current situation is , ever since I got to Endgame, I am getting Abyss basically every map. And the entry to the Depths opens at least 2/3s of the time? I just think getting the depths should be a more rare occasion, so that it is actually exciting to see the hole instead of it being what can be expected?

It's RNG. I used to get the depths almost every map and thought that was normal. For the last week or so they have become rare for me for some reason like 1 in 10 maps.
