Maybe the Federation don't want you ranking up and stealing their ship before flying it into someone else's territory? Keep the range down and keep the less determined people protecting Federation space with it.
It's possible even with a meagre jump range like the Corvette to travel across human space in an hour or two. Stripped down for fast travelling that halves to 30min-1hr
max travel time. Provided you don't expect to move everytime you play I don't see the problem. If you want a fast moving heavy hitting ship the Anaconda is there for that. Make the Corvette/cutter have a bigger range and the Anaconda has no purpose left.
I mean crikey, several people have taken a Corvette to Beagle Point, all of 65,000Ly. If they can why can others not? I sympathise for those with limited playtime but I'd ask the two questions how they'd got that high with limited playtime and why they'd chose a ship with low jump range. Realistically only those with pretty high playtime get a Corvette and therefore should be able to sacrifice an hour or two to put it where they want it and fly other ships to-from it when they wish to travel.
Ah well 2.1 may make it easier with engineers, ship transfers are supposedly coming soon too so my personal opinion is wait and see, if prior to 3.0 people are still unhappy then lets ask the question again, with all the current changes planned for me the question is moot.
Edit: Above point stands, 33 pages no resolution. Opening a new thread expecting different results is ambitions at best

I can see why people want a jump range buff but I personally do not see the need.
