I brought up the issue regarding Predatory Strikes and AP/FAP on the german forums a while ago when Build 8905 came out. Back then, people reported that the PS bonus only affected the FAP portion of the weapon even though the tooltip says 'ANY AP'. Additionally, there was a bug with PS which caused the bonus to fail in case the weapon was equipped being in feral form already, for example, when you switch back from your healing mace.
In case PS works with ANY AP on a weapon, the change of Strength to AP on the Feral Staves might not be so bad overall as PS even overcompensates for the lack of raid buff scaling.
Does anyone have up-to-date information regarding the exact mechanics of Predatory Strikes? Everyone seems to have different infos
As for the WG 'Nerf'. I don't quite understand what's so utterly bad about this. Everything it does is forcing us to use it only when it has run out leading to the most efficient use of it rather than inefficient spamming.
