Speaking as primarily a cutter pilot when given the option between the two, I am still pining for the kind of combat that lets a 'vette show its strengths.
All you have to do is fight ships that are faster than the Cutter, or that the Cutter has difficulty pointing at.
There are very few things that a Corvette has near zero time-on-target against, but there are plenty that a Cutter, even one with copious use of gimbals and turrets, will have trouble even engaging.
I am talking content such as defending an area, crowd control...basically any combat with actual context. Something that lets the vette's mighty agility work without its low speed hampering it.
For now, we have to find our own context, but more content that encouraged this from time to time would certainly be welcome.
