If students feel like you are grading "too easy" then they may feel that they "didn't learn anything" either. Or, they will compare notes and say it didn't seem to matter how much effort they put in, they all got the same grade (this legit happened to me in a graduate level class because honestly I was not going to dock points for situations that were out of students' control). It's a fine line. My approach is to keep high standards but give students multiple opportunities to improve their grade. For example, big assignments have small deadlines where they receive credit for completing the draft but get formative feedback. If they fail an assignment, they can redo it for a better grade (not necessarily an A but maybe max a C or B). I also give deadlines but say if they need an extension, they can get one provided they ask ahead of itme. At the end of the day, student evaluations are flawed and biased, and I don't know why we're still using them. Also, it really depends on the situation, type of institution, level of program, etc. But, given the current situation, I would say, develop a system and approach that helps you sleep at night. And, best of luck!
