Thanks for the comments guys. Nice catch rain, how did I ever miss that character advancement was in Starships: Book 2.
Anyways, now I understand why people were so ready to abuse the instruction skill. Those rules are pretty spartan.
It isn't really that I have a problem with character advancement being slow, I just think it sets a bad precedent for advancement to focus so much on money and off duty time. The reason I don't really like it is that there ends up being no real reason to adventure if cash and time are in abundance. Characters sit around "training" and making "dedication" rolls in outside pursuits. Unless your going to run out of money, there's no real reason to go adventuring. When adventures are afoot, the focus becomes "shoot your way in as fast as you can and get the money." High tech solutions end up being an even worse cop out, as they usually end up being some formula of "spend X credits and Y amount of time at the 'total recall' facility and get your +stats or skills; lather rise repeat.
I would much rather the characters felt motivated to use their skills, whether that is simply putting themselves in situations where the skills are going to be used or finding creative uses for their existing skills. Get more skill rolls in - get more experience and thus more proficiency.
I think the rules as written really tends to screw characters who get denied early for reenlistment in the proir services also. Take for example a guy that has a few bad rolls and gets drafted in the Army. No commission, 2 measly skills and an unlikely chance to reenlist. Still just a kid at 22, but he is expected to survive off virtually no cash, 2 skills and no chance for self improvement in game. I understand that part of the fun of Traveller is making characters that are random so as not to be cookie cutter, but I don't want to have to make a career out of rolling up characters to get a playable one.
That's sorta my rationale for Traveller needing an on the fly experience system, like my tickmark one above.
BTW, excellent suggestion robject. I think scaling the tickmarks is a potentially a good idea.
Anyways thanks for the suggestions guys.
