are these even finished? or still a work in progress?
As far as I know, these are still under development. I've been using them for a long time, from when they weren't Ace2 based, and when they were strictly for Hunters.
Since Sorren has taken development back up, it has expanded to support other classes, but is still pretty beta. I've noticed mine sometimes doesn't catch Stings, so there is likely to be some other outstanding bugs out there.
