Cryptic reported that the data collected after OB showed that one player put in 190+ hours, or 8 days worth of playtime. They didn't mention what rank he got too. It's not really possible to gauge this because it really all depends on how you play. How much time you spend on Sol Station, your chatting time, what missions you do and/or don't do, in what order you do them....the list goes on. On some of my toons I played for 10 hours or so and only got to Lt 5 or 6 other times 10 hours got me to Lt 8. It really dpends on alot of various factors.
