Ahhh I see. That's a good point, it is flavorful that a giant and slow block would be easy to hit.Edit: For example: the gelatineous cube is a level 5 brute in 4e with plain old AC 18.
In 5e it has AC 6. Which could have never happened in 4e, because it is totally out of bounds. I really love that design.
Feels more like an issue of scale than of principles to me, though. Of course, in 4e we didn't have bound accuracy so I don't think you can compare numbers quite that easily, but the idea of the Cube being way way easier to hit is not something that impossible.
Design principles can always be bent to make some interesting monsters, it's not like someone will punish the designers for going out of bound or doing something wonky from time time.
