Shrimp from unranked to B-Tier
I think shrimp is the best pizza topping for seafood lovers. Goes well especially with garlic. High amount of people allergic to it kinda sucks though.
Bacon to A-Tier.
Bacon good, that fatty taste goes well with cheese. Besides, who doesn't like bacon (besides vegans and vegetarians)?
Also I think mozzarella cheese should be separated from extra cheese. It's the best type of cheese for pizza and deserves its own ranking (S-Tier).
Not a fan of pepperoni and thought of proposing to move it down but I'd probably get a lot of hate for that so nahhh.
