why is the villagers so bugged and the end isnt very fun

villagers seem to go for beds out of reach or not with a viable path they always get stuck in the walls and just break if theres more then 20 me and a lot of other people really need a villager ai rework make it near the one we have but just less glitchy also we need more jobs for them and more content also there should be 2 new structures in the end the end feels very very flat with bad floating island generation and only 2 structures being the end city and the end gate which i dont think even is a structure there should be atleast 1 to 2 new biomes to make it not look like the old nether and maybe even a new end fight design and a endermite rework i appreaciate the new dimmension but we cant forget the old ones
