I'm trying to get back into crafting after not doing so for about a year lol. All my DoH are 50 with the exception of a couple classes I got to 55.

What I wanna know is if there are any hints and tips when it comes to levelling up.
--Is there a specific order as to what to level up first, second, third, etc?
--Are there any good EXP leves? Something that doesn't require a bajillion steps each with a bazillion mats?
-- Basically, what's the most efficient way for you found to level up?

Thanks!
