Sure why not. I like to get more nuanced with tiering, so mind the large image. A few things to note are from this:

-This is aimed at PvP, considering both 1v1 and teamfight viability. I don't factor PvE since not only would that skew results all over the place, most classes work there anyways, so it doesn't feel too relevant to me to include.
-For the sake of fairness, all of these classes are to be assumed to played and built perfectly optimally. This disregards skill floors/ceilings mind you, and is focused on the exact mechanical merit of what classes bring to the table, and their overall consistency.
-Obviously what gets paired with what affects the combination's viability, so I structured this list to account for that. If you want a rough estimate where each "actual" tier is, I group the colors based on what I believe are within the same ballpark of strength.
