I still don't exactly understand why one couldn't just use (x, y) vectors;
You *are* just using (x,y) rsp. (angle, radius) vectors. You can completely ignore the meaning of i as sqrt(-1) and just view "i" as the funny name of the second axis in a 2d-coordinate system. Instead of calling one axis the x-axis and the other the y-axis you call one axis the real and the other the imaginary axis. That's all there is to it. It's nothing complex (pun intended).
