Yeah, they're there.
I never liked the concept of experience points in Traveller. It was a design concept for D&D and similar games to reflect your improvement with your weapon over various bad guys and what not, but it seen became the "real game reward" which was never meant to be the case. The game and achieving the goal was the reward, not the exp pts. you earned.
But soon the game became all about killing stuff for experience. Plot, story and general experience suddenly didn't mean a whole lot.
Traveller took a pragmatic approach to the concept, so as not to make it an issue. I like it that way.
Yes, DnD promoted the concept of being "murder hobos" just wandering around and killing stuff, while the deadliness of trav combat made everyone more leery of it; quite the opposite situation.
