Apparently the definition is confused because I quite commonly see “it’s not overpowered, it just needs some tweaks”. Being overpowered means that it needs to be tweaked down to normal power levels. I don’t know why you people think that if something only needs tweaks, that it’s not overpowered. If normal is 50, being 53 is overpowered, being 82 is overpowered, being 407 is overpowered, being 50.6 is overpowered. All these things can be fixed with tweaks.
Can we please stop saying “it’s not overpowered” and following it with “it just needs some tweaking” now? There are only 3 things anything can be: “balanced”, “overpowered”, and “underpowered”. And from what I can tell from what I’ve seen from TRS, Balanced falls in the 48-52% WLR. Which means above 52% is overpowered and below 48% is underpowered.
