As far as squid spawning goes, I completely agree with you. After teleporting to a new location in the ocean, I generally encounter 500+ squid and once it was over 700. Eventually they will despawn, allowing new ones to spawn and thus continuing the cycle. I even downgraded to 27.2 and it seemed that the squids were just as big of a problem back then as they are now.

In regards to mobs collecting in certain areas, I don't doubt that it is happening for you and many others, I just haven't noticed it myself.
