I realized that (at least some) drakewatcher manusscripts are not assigned to primal storm bosses.

For example I miss "Renewed Proto-Drake: Purple Hair", which can drop from Pipspark Thundersnap, but ATT does not show this.

I noticed primal storm rares generally are missing a lot of info from various addons like silverdragon ATT handynotes etc
Wonder if their loot tables are unclear or something.. idk :)
