Should a designer be able to draw? Russian point of view

Knowing me someone could say: “Obviously, you think that should. Since you can draw, you think everyone should.”

Well, not exactly. A designer doesn’t need to be able to do anything, but to be a good designer.
The only thing is that design is a very highly tailored thing and for majority of designers to be “only a designer” is not enough.
In big companies, where're many people and a lot of work, it is possible for one to design only. A designer doesn’t have to be able to draw - they have illustrators, as well as coders and programmers, and they know how to do their job faster and better.

Unfortunately, “just a designer”, if he is not doing anything else besides designing, seldom is satisfied with his job. A good designer doesn’t have to be able to draw, but he should be a creative person who studies works of others, trends, styles, different useful things about colors, fonts, and has plenty of ideas. A person like that usually grows out of “just design” and wants something more serious, interesting and many-sided.
However, even in this case a designer doesn’t have to become an illustrator. He might become an art-director; get interested in ad graphics, advertising, flash, computer languages, 3D, audio, video, etc. and be very successful.
Than why does a design major requires drawing??? Because there is a level of ability to draw that everyone on the planet sooner or later can learn. Obviously, best part of quality educational institutions think it’s never bad idea for a designer to learn elementary drawing skills. That is why majority of people that have a design degree can draw. At least, these people never ask themselves if a designer should be able to draw.
