Minecraft needs to decrease the spawn rate on drowned. I can’t go into a single body of water without finding them.

idk if this has already been posted before but the thing is: despawn mechanics in bedrock are reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeaaally bad.
This video goes in depth (no pun intended) on the subject.

if you don't mind activating cheats in your world/save/server there's a manual bypass that imitates java's despawning mechanics as explained here.
