There is also a lot unnecessary fear of change when it comes to design and UI. I used to have the same fears, but after working with analytics and AB testing, I realize that they are mostly unfounded. 90% of the time the changes are not going to have much of an impact either way outside of superficial user behavior that doesn't impact the bottom line. It doesn't matter nearly as much as you think in most cases. A lot of design is BS but there is even more BS coming from those fearing change.
