So I have this online course?

So I have a course I'm taking online called RE-103-OC1 Love and it's Myths with Professor Marybeth White that I am taking online and tbh I hate it. The lessons are bland with a lot of reading and definition work and it takes up a majority of my time as opposed to the other 4 courses that I'm taking along with it this semester. I just saw the update that Nov 8th is the last day that courses can be dropped without failure or possible tuition adjustments. I have a 100% courseload right now so going down to 80% will definitely still mean that I am above the threshold for FT studies and receiving ft funding for it but I was wondering if there are any drawbacks to doing so?
