Don't worry about it. Ships are paid with energy credits. Just do what you do and you'll have a pile of credits in no time. The stuff is only good for ships and white gear. So, it piles up fast. I'm LtCmdr/4 and have over 44k of the stuff now.
The problem is, I'm not going to waste skill points on "Bird of Prey Captain" and "Raptor Captain" skills. So, basically I'll be gimped until T3 or they release the t2 cruiser. The idea of grinding through lt cmd to commander with a gimped loadout and skill layout is really unappealing to me.
Making a T2 cruiser really should have been a high priority for Cryptic. It is core. Fail.
So too the raptor, since it's also taken from the Enterprise series Given that it was included in STO means anything's possible.
Which is something that was always ridicilous in my opinion.
The real reason behind the fact that the Klingons kept using older ships in TNG and later
was the budget, which is the same reason the Bird of Prey was scaled up during TNG several times.
A very good article aboutwhy it makes no sense to keep using an old ship beyond a certain point can be found here:
I'm sure the fact that the K't'inga has, by the period Star Trek Online takes place, solidered on for another four decades beyond what is written in that article and still remains in use as a frontline combat vessel would give Bernd Schneider fits.
Ship classes in Star Trek just have a lot more longevity than contemporary military equipment, for whatever in-universe reason is required to explain what was clearly something done for budget reasons in the shows.
