That's kind of just how scaling works. I'm pretty sure a lot of people feel odd about a random robot that gets hurt by bad words as 3-A, but it doesn't stop the fact he has the feats to support his scaling.I agree with you that most of the times these things are game mechanics or just things made for the sake of the game, but what I don't like is the snowball effect that comes from accepting the thing.
Mario is unscated by Brobot wiping out thousands of solar systems > Brobot and others things can harm Mario > All of them are now superior to that explosion.
I mean, I know that the word is hated, but couldn't it really be an outlier or another case of mechanics/inconsistent thing?
I'm definitely more likely to believe that instead of scaling all of them over that small and isolated thing. (I'm not even convinced that it actually destroyed a 4-A structure, but this doesn't matter)
It would really only be an outlier if the King Boo and Power Star stuff get rejected, otherwise, they're just going to keep their 4-A ratings with this as yet another supporting feat with the others they have. Isolated would not really be the right word in that context because it'd be a repeated thing they've shown to be comparable to.
