I finished of my ALC, CUL, CRP, and LTW using Daily Ixal quests only. I flagged them on those classes, crafted the items w/ my Fully Melded Armorer, ran back to the camp as my WAR (Just to make sure I didn't hand in as the wrong class) Swap o desired lower level class, hand in quests.
6 hand-ins (doing ighes to tiers) would give you 75%-80% a level, so every third or fourth day you might not level up, but in about 10-12 days I would go from 40-50 using Ixal alone. I did this pre-2.4 which resulted in my Oaknot stockpile, which I used to craft my ARM, BSM Atisan Secondary tools, and my Foragers Sledgehammer. post 2.4 I was finishing CUL, and go the mats for my Artisan's Feet/Legs/Mitts. I still do them every day, just on my ARM, I will use the oaknots eventually to make all of my Artisan Secondaries, now that my main classes are covered.
