[Already failed to provide Pro and Con; damn no edit button]
Advantage: You can fast level to lv 60 in a day with bare essentials.
Disadvantage: If you don’t already have a solid support from friends / if you’re soloing, you will find it difficult sustaining your character at high levels. IE; you may not have enough gold for equipment repairs, or event potions.
Ideal and practicality? This may be good if you already have a solid, self-sustaining, main character and just need a quick high level character for whatever reasons.
Should also point out; I plan on doing more detailed guides that this one did not cover. In Example; gold/coin farming.
