Enhanced Card Nerf?

So about the changes to Balance and Bole (20%), is Enhanced Royal Road useless for these two cause idk if it's a text bug or that the developers didn't want a 30% damage increase / damage reduction buff. It just makes enhanced royal road lose one of its pros

Enhanced should increase the buff to 30%.

I think it just a text error, just like the nocturnal ST heal barrier, it still say 130% instead of 170%
