Kundela slash is fine as long as you land 2 debuffs, you only really need curse for bosses and that’s what bone pointing can do. Kurdaitcha will become an aoe DoT too so you still get some AoE compensation out of it. Bone pointing will also have better uptime since they raised its duration (assuming they keep the cd the same). No idea if it will hit in an aoe since they added aoe ratio, if it does then that makes it really good for applying curse, in addition to properly doing damage.
I will probably change my build to FF-Sorc-Necro when this patch hits, assuming I’m still playing by that time. I will at least update the guide though.
