There's many benefits to using leveling guides for SWTOR. There are hundreds of thousands of players enjoying this game and spending far too much time on it, and competing with them is nearly impossible unless you have 10+ hours per day to play. As we all know leveling characters is possibly the single most important thing in Star Wars: The Old Republic or any MMORPG game for that matter, and doing it as fast as possible is preferable to most.
That's why there are some professional SWTOR leveling guides out there that are made to help you do just that, level up quickly. They show you an optimized leveling path that includes only the quests and missions with highest and easiest experience gains so you can level up quicker than most other players. Such guides are extremely popular and most players are reluctant to give you information on which ones worked good for them as they don't want everyone to know their secret leveling methods.
