I haven't been playing long enough to come up with a list of 9, but this is what I have from my initial impressions.

Short:
1.Rank titles. I'm new to the franchise and don't know much about naval command structure, but the more Star Trek I consume the stupider putting admiralty titles in the normal progression seems.

Medium:
1.Levelling Rate. It's just way, way too fast. I just got a third of a level from scanning 5 things. No fighting, just walking and scanning. Methinks it should take about a couple of months to get from 1-50 with heavy play, but I don't really know what the ideal balance would be.

2.The ability to choose the order one does Feature Episodes. This is just because I got my first character to near the end of the Klingon missions before restarting (I tend not to use my first character for long in any MMORPG). Would've been nice to have been able to start on a different narrative.

Long:
1.Ship interiors with basic facilities, shipboard missions and inter-system navigation. 'Cause the inside of the ship is an important part of Trek and Sector Space is kinda terrible.
