They were never able to fix the scaling to work properly, so the Arms/Legs were left at their level 75 base. Use Highwater legs/arms or get raid stuff.
They removed the scaling focus because it wasn't working. Legs should be Fero X now and arms Cleave VII 26
Thanks and bummer. On the raw crypt-hunter it's Cleave 27 and Fero XI so it looks like the legs are worth wearing over the highwater.
