Realistically, you could do them all. But...There are Six crafting professions and I want to have characters who develop different skills. I would rather have two characters develop 3 craftings skills each but I wonder if this is realistic. Should I do 3 characters:2 skills each?
You can get skill points merely for exploring. Both XP and Skyshards.I am surprised to by this answer, isn't there a lvl cap therefore making it difficult to develop too many different skill lines? Your skill point being limited, forces you to be economical with how you develop. Is this not true?
