I would like to see both. Maybe 1.12av normally, and 1.5av on AV weekends. People don’t seem to remember that almost no one did AV before the revamp because it took 12 hours. It was fun to do once in a while, but it was terrible for honor.
In any case, 1.12 AV was always going to happen, they’d have had to reconstruct 1.5 AV, which would have taken man hours. Man hours cost money, and every single decision they’ve made (that I can think of) has come down on the side of whichever is the cheaper option.
