If the class is easy, then the half letter grade won't matter much and nearly everyone will get high scores, rendering attendance useless. If the class is curved, then boosting those that attend is functionally the same as penalizing those that do not.

Classes shouldn't be easy. I had the privilege as an American of studying at a university abroad that used the English system of marks, where a top grade began at 75%, and that was difficult to attain. The quality of education I received there was exemplary, and the grades were not inflated, at least not to the extent I've seen at American universities.
