I intended to screenshot this after my guild's raid win today but forgot since I was distracted by crafting the gear. Eitherway, this has been an issue since the launch of the raid I was hoping it would get fixed this last patch. The Balance HunHau's Vacuum Mail, the lvl 160 version is missing power pip chance. I believe it should be about 9% I am estimating since the death gear often is similar. The 170 version does have power pip chance it is only the 160 that does not.
These are the kind of issues that can easily be caught and fixed if the gear crafter for crying sky raid was at the guild house. If the only issue is the crafter would get filled up, make cantrips a seperate crafter and add seperate raid tabs. This is much more future proof and a clean solution for all gear. Never should you have to complete an entire raid to go back to craft.
