Not to piggyback on the back of the things Aisi said, but they explained a lot of my issues with this tier list, better than I possibly could.
It can't cover all the possible circumstance of an actual match as it plays out,and you cant look at everything in a vacuum so its hard to make an objective tier list.
You'd be better off just making a tier list of your own opinion on the balance of said classes instead of trying to make an "objective" that doesn't consider most everything.
