Let me put it this way. Classification should not be up to the modmaker conserning his mod (if they are to be vanilla balanced). Heck, I could create a "frigate" that is on par with a Hegemony "Capital Ship".
Instead, classifications are universal.
Like the little Scarab from Starfarer Extended, running about with it's large ballistic slot?
That thing.
First time loading up Omega's Minimash, bump heads with one of those ships in a Lasher, get all high and mighty because it's one on one and it looks flimsy. Suddenly, NOPE'd by a crazy frigate gunboat with an Autopulse Laser. That showed me.
And I play with the DSTech mod installed, vanilla balance goes out the window. The Judgement destroyer in it's 'Anti-Capital' loadout uses a weapon not unlike the Tachyon Lance, except it does more damage over time, shoots faster, has 8000 range instead of 5000, and the Judgement itself moves at around 150-200 or so, even while firing, so even as the long-range sniper that it is, it never has to worry about being harassed. Even if it is attacked, it can just turn it's sniper beam on the harasser. Luv me DSTech ships.
