So hey guys, now that the dust has settled on pre-patch Im wondering if there has been any discoveries that matters. For now I think my best way would be:
Get Dalaran HS quickly (Useful for extra portal back to capital)>Then start WOD questing until level 40, and then focus on herb/mining 40-50. So you make that new allied race, get its heirlooms enchanted ofc, then pick up mining/herb, maybe buy some bags and send over 10k gold and off you go.
I have 10 characters (all the allied races) to level so I also plan to level them using rested XP. I tested 48-49 mining/herbing in Azsuna with 310% flying, and no XP buffs and that was 19 minutes with probably not the best route, so maybe if you really go hard with tomtom herb routes and the XP potion etc. you can do that level a little bit faster.
Im not sure if I can think of anything faster. I find 5 mans in WOD to be waste of time / over-tuned, so they are to slow, and Im not sure if its ever worth going around doing only bonus objectives over normal questing even in Gorgrond.
So my I idea is just to rely on rested XP, especially 40-50 herb/mining where you get 1-2k xp. pr herb depending on your level, 2k XP at 48.
