I wouldn't even post example potencies. It's completely meaningless. The devs are the ones with the gameplay formulas and gameplay testing teams. How are you supposed to figure out what the correct potency should be? All the potencies changed this expansion. They're entirely relative numbers set by the devs.

And like you said, you always run the risk of running into that person who did a first year math course in college that one time and feels the need to flex their introductory math skills. They might even own a graphing calculator that they don't entirely know how to use properly and be part of a theorycrafting circle. That road leads to a long, boring conversation with lots of quotation boxes that have nothing to do with your original post. Please don't do it, for all of our sakes. Just leave out the potencies and talk in general terms. You're a consumer. What do you like, what don't you like? What is your subjective opinion? If it's a long list, do it as a bullet problem/solution list so that people with shorter attention spans can make it to the bottom.
