leveling is pretty quick if you skip all the cut scenes
SInce I really enjoy the questing in SWTOR I try to do all the quests/FP's, but for me it also feels a little bit too fast (leveling my first char, a jedi sage). Without rushing and while leveling my professions (not to mention the countless hours of searching for FP groups :/ ) it took me about 25-30 hours. Guess you can cut a lot of time by skipping the cut scenes, but I think they are just too good.
I'm just about to try it out, i really want to get to the cap fast, i have had enough from leveling in WoW
