the greatest limitation of a solo bomber is that it takes time to recharge the energy to fire a second SN shot - in that time, the shields of the truely big warships can replenish enough ( or recharge when depleted ) - so the bomber is forced to at least fight in a team.
if a bomber can fire 2 at once - it can keep the shields of a capship down much easier. ( i know a bomber can currently mount a razor and a SN for this purpose - but a razor is "only" 20k damage - and not 137k )
i do strongly suggest not to create such ships. ( not about the model, but about the suggested stats ) - we all do know that capital ships are weak as they are. - we should not make it worse to create a ship that can basicly solo them - if we are true to RP and teamplay, - we should rather make sure that a bomber needs a team, rather than be able to take down any warship it wants - alone.
currently, i can deplete the shields of a cruiser ... all by myself in a single bomber. - when i mount a razor, i can even solo a cruiser. - this is not right, it doesn t feel right - it just makes me gloat over the poor capital ship. - so unless such a bomber has really the mobility of a battlecruiser and an energy regeneration of a starflier, it ll make a mess out of the balance ( thats of course exaggerated - but thats how i feel when i see such concepts )
if you want something vastly different - give it the ability to mount and fire 4 gunboat foreward cannons. - ( since it d have so much energy then - give it only 2 lvl5 turret mounts as secondary weapons ) that way, you d have a specialized and not overpowered ship. such guns would be much easier to hit with - and due to the fact that they are 4, could keep a shield down and do damage still - while not doing what.... 4x 137.000 damage.
anyway - such a ship should be dead meat ( literally ) against defensive fire. - it should be as agile as a cruiser at most - so they cannot be used solo.
and yes, i do fear the anti-cap and "cap-whore-yelling" part of the community a little.
