MM will want to keep its points in Careful Aim despite the nerf, but what about BM and SV, specs for which CA is weaker? At least according to tentative results from a warf that’s been femaled, BM should keep points in CA (like this) if the PTR change goes live. SV will be better off putting three points in OWN, two in SE and zero in CA (like this). This is categorically true in my estimation for SV hunters with cunning pets. SV hunters with ferocity pets will want to have their pets have at least one point in Wild Hunt (rather than going 2/2 Shark Attack). The best SV results I found were with the SV spec I recommend and a ferocity pet with one point in Wild Hunt and one in Shark attack (like this).
Note that these results were found using my gear and the femaledwarf setting that allows you to manipulate the percentage of the fight spent in CA range. I reduced it from 20% to 10%. I additionally disabled AS during CA. Note also that these results assume a tank and spank fight and that I committed no errors. Thanks as always to Zeherah.
