You can still use PO2 to play though I'm not exactly sure if all bugs were fixed :OSorry but someone is going to have to take my place :x NBS isn't cooperating
I'm not sure if PO2 has 100% acceptable mechanics yet. Any bugs they have at the moment are definitely hard to notice, but I think moves like Hypnosis might have wrong accuracy and that Wrap mechanics might be slightly off. Plus the tooltips for many RBY moves show all sorts of wrong information (30% para for Thunder, 10% burn for Fire Blast, and more), and I don't really know if these wrong tooltips equate to wrong mechanics since buggy proc rates are difficult to notice.You can still use PO2 to play though I'm not exactly sure if all bugs were fixed :O
