While making this change, we also put in a one level shift down in the display value. Characters now level from “Ensign 0” to “Vice Admiral 50”. The reason we made this shift was so that characters rank up on the levels divisible by 10. For example, a Starfleet officer achieves Lt Commander at level 10, Commander at level 20, Captain at level 30, Rear Admiral at level 40, and Vice Admiral at level 50. We believe that this will feel more natural to players, and it made sense to make this shift at the same time that we were changing to display the actual level.
This is a great change and will help clarify why "Commander 0" doesn't actually award a promotion as one might expect. I support this update. However, as others suggested, it might be better to decouple the ranking system altogether. At the very least display it as something closer to:
Level 36 (Rank: Commander)
If time and development permit, it would be nice to set your "Rank" separate from your actual level (i.e. allow me to show "Level 50 (Captain)" to other players, and not just "Level 50 (Vice Admiral)" when I'm wearing captain pips)
