Really confused about this, how is one supposed to draw with the entire arm on a small tablet? at 100% zoom, drawing requires minimal movement, its much more comfortable with such a distance to draw using the wrist, the only time i can even use my entire arm with broad strokes is when the canvas is at 800% zoom. seems unintuitive and weird, im positive people cant be drawing this way, seems retarded..

am i missing something technique-wise, is this a tablet issue, just need more practice? is it acceptable to draw from the wrist? what do to improve line quality.
