To make this as fair as possible, I am not naming any names even though the person is not at fault, but I have stumbled across a recent edit on the Meta Power Opposition ability, and you have removed the Super-Adaptoid without even leaving a notice message.
This desperately needs to be a rule at this point, and the issue is getting beyond the pale at this point.
Throughout all the wikis under FANDOM's brand, the editor comes with a 'reason for edit' text box, and it's invented for a reason for why the edits should apply, as well as with reversing them.
