Whenever someone makes a post like this, it always comes off as sour grapes…
“I wanted to be a car designer but…turns out I didn’t build the necessary skill base and now I’m going to go off”
This has been hashed and re hashed on here about 456,022 times. I think the general consensus on these boards, and in most of the industry, is that sketching and rendering are communications tools. They can communicate a bad idea just as easily as a good idea. In a battle of the sketches, a great sketch of a bad idea might beat a bad sketch of a good idea… so just make sure you sketch your good ideas well, and leave the bad ideas off the presentation.
It is one of the core communication tools of a good designer designer and it is the responsibility to the the designer to use it properly. You can like it or not, point to bad sketches by good designer, and wine endlessly, but it doesn’t change these realities.

Sketching is not an enemy of design. Lack of vision is.
