Phantoms swoop into the water

Since they were in the aquatic update they should do something with water. They are stingray-looking things after all. So I think that phantoms should swoop into the water to attack players and fish that are 1-4 blocks in the water. They should also spawn in deep oceans. This may sound a bit over powered but if they miss their target, they are forced to very slowly swim to the surface, leaving time for the player to attack
