Leveling guides are typically used for MMORPG games, where leveling your characters is a big part of the game and staying ahead of other players, especially at game launch is really important. In essence Diablo 3 isn’t much different from your typical online RPG game.
There are thousands of players who have way more time than you do and if you want to stay competitive in this game, you will need some kind of an edge.

However, that’s why there are several paid D3 leveling guides that will help you gain an advantage over other players.
Having such a useful leveling guide to show you exactly where you should go and how to maximize your character’s potential is extremely beneficial to being good in this game. If you want to start dominating other players online than knowing the exact strategies for boss fights, class vs. class tactics, equipment drops and more is essential.
