Long time player here (despite my forums character)
I also agree with the OP. While 1.12 AV isn’t necessarily a terrible option, turtle AV’s are something I (and probably many others) never got to experience. A good compromise in my opinion is to have both as separate BG’s. This way both parties can be satisfied.
But if it were my choice, and I wanted the closest recreation of vanilla that I could get, then it’s a no brainer.
