I'd suggest that you level up your crafters with leves under lv50 and also use the ixali beast tribe quests to gain some experience. At 50+ I can only recommend doing collectable turn ins, which grant you not only xp but also red scrips which you can exchange for various stuff like gear, mats and even 150% xp boosts. Also to note: making collectables is easier then HQ'ing materials. So you definetly want to unlock Rowenas house of splendors (which are used for collectable turn ins)
