Please keep in mind that this is all opinionated. Most of you may disagree with this tier list but at the end of the day, it's still just a tier list. My goal in this tier list is to give others a general view of how good or meh each servant is. As others may say, there is no bad servants, only bad masters, whether you believe that or not, it's all dependent on you. Everyone can work as long as you can go do big brain strategies with the servants, especially those listed below the list.
I shall elaborate on why they are placed in the said tier list as soon as possible, but as of now, this is a work in progress
