we shouldn t try to recalibrate every shipclass in the entire game.
furthermore, one should not base stats on the popularity of ships ( even if it was done in the past )
if you run the statistics, you d see that light fighters are roughly as numerous as battleships ( by numbers ) - so we shouldn t attempt to say "buff light fighters to be used by more players, cause they re unpopular".
the cruise speed as such is an "absolute" speed. - giving ships too much advantage in that department turns them to become near invincible.
right now, a light fighter that knows how to dodge can escape a lot of damage in a pure melee - when we buff up the cruise further, they can also escape from everyone. - and while it might be quite a satisfaction for a "light" fighter to kill a larger ship... one should also look at the other side.
no matter how small your weapon and armour, when you re impossible to hit ( unless you run into a nuke mine by your own mistake ) you can chew your opponents armour away in a very long and very boring dogfight.
think of it - a liberator fights a nomad voidrunner ( meaning the best public LF vs. the best LF in the entire game ) - the dogfight is supposed to be fun. - and while the keeper fighter can still fire a minirazor - he is unlikely to ever hit ( but i think he can also drop a nuke mine as it has a minedropper, too ) - but if both pilots are equally highly skilled, the fight can go on and on and on and on.... for hours.
is that fun?
light fighters might not be as popular as VHF, and thats - at least from my point of view - a blessing. fighting them is more frustrating than any other ship.
when it comes to opinions about cruise - there is no logic one way or another. - for example in star trek / star wars - the larger ships are faster than the small ships. the small ships are more agile, but whats agility when you fight weapons that travel at lightspeed or faster anyway....
for example, the kusari dragons engines take up like 10% of the ships mass ( they are those two little tubes ) - the liberty dreadnoughts engine takes up roughly 30% of the ships mass - one might think that the liberty dreadnought is faster than the dragon - but not more agile of course.
in space - the mass of a ship or its size is rather meaningless ( unless it produces its own gravity well ) - the mass only affects the acceleration, but not the top speed.
