Just the fact that it was revamped a long time ago doesn't change that its art is great and perfectly up to site standards. An unnecessary revamp isn't the way to go to give something new life.
And why does this only happen with the Otachie? x3 I can think of plenty of Creatu that haven't been revamped in a long time/at all, but no one ever complains about them. It's always the Otachie. What, because it's common?
Otachie have the same quality and the same style as all the other pets released around that time. Uilus, Meiko, Liyure.. We don't complain about them, so we shouldn't complain about the Otachie. ;c
