But it's still worth it, especially for crafting leves. If you want to specialize in 1 craft at first you can certainly get leves for that craft from each nation since nations only really give 2-3 leves for each profession at the lower levels. Not sure how that translates to the higher levels though. I would think that guilds will have a play in that in the future.
Going off-topic here, but I wanted to reply to this. The Crafting leves are one time only, but more become available when you rank up your Craft. I noticed that I got a new leve available at near Rank 20 Armorer from the same person I did the lower Rank leve. They probably don't show until you complete the lower rank or are higher rank yourself.
I just wanted to add, you can do 8 BATTLE/GATHERING leves, and 8 CRAFTING leves. so 16 total. Doesnt matter where they are from.
Is this true? I hope it is because I am always worried about whether I should take the free crafting EXP and just grind my DoW, or try to split it 4/4 every 48 hours. Can anyone confirm?
