Yup. BGS thinks the same way I do and says it ruins good level design. No levitation comfirmed.
The only way levitation ruins good level design is if the level wasn't designed with levitation in mind. Using "ruining good level design" is just an excuse. You could design good levels
with levitation in mind and be just fine, or better yet, design levitation so that it cannot be misused.
I personally loved it in Morrowind when I found secret caves that had treasure that you could only reach
with levitate.
