When World of Warcraft was 1st released it took me 3 months to get to level 60, it has taken me 2 weeks to get to 50. I have found it much easier and faster to level in SWTOR. The only quests I have not done whilst leveling, are those that require a group ie heroics and flashpoints. Do i feel, that i have missed out? No not really, I have quietly leveled just doing questing, no rushing and instead of spending hours looking for groups and having instance entry bugs, I have just quietly done missions.
