It’s not really comparable to a woodie that received new trains where you’re still sat in the same position. Mantis you ride the coaster stood up, with a floor. Rougarou you ride sitting without a floor. Two different riding experiences. But then I suppose you also have those old togo coasters that had both a stand up and a sit down train.
Consider it a new cred if you like, the beauty of counting creds is that you can decide yourself if you’ll count it or not.
