I like the new element but i also agree they spawn way too much, they spawn almost everywhere in my long term survival, plus they are spawning all around my buildings and my 2 settlements, nowhere near and not within 100 blocks of villages.
I Started 3 new survival worlds to see if it was just that one world but nope within a few minutes i am getting attacked and killed by illagers and the illager beast.
Have no idea about the head movement, radius does seem to be higher for the beast, And I can reproduce with other mobs too.
