yes - bomber should be better vs. capships... BUT not require less skill
i would always support it when capital ships had tiny "weak spots" - that would actually destroy the ship in only a few hits.
but a bomber hitting vaguely "somewhere" all around the hull ... sometimes on a little fin or thick armour shouldn t cause much damage.
if bombers were forced to actually AIM and WORK for their kill vs. capships, - no problem to have a battleship die to 3 supernovas. -... IF the supernovas hit small subsystems!
you wouldn t need 10 bombers to kill a battleship, but yes - 10 bombers would increase the chance that one of them hits t he weak spot.
if battleships could only be disabled by destroying their subsystems - but were immune to hull hits. - you could virtually decrease the hitpoints of the subsystems to a bare minium.
that way - you d probably end up actually using the nova torpedo, cause 90% of the bomberpilots are not good enough to aim with their supernova - most of them wouldn t even hit a turret the size of battlerazor from 1k... ( come to that - many players never really pick subsystems at all )
but as long as you can hit the battleship whereever you like - it is very easy.
