This is indeed the question I had for a long time. They occupy the entire front section, cost tons of energy and deal roughly 1.5 times more damage that any endgame weapon put in L slot. They are useless in close combat and have a long death-star-charge-thing window before doing anything. So... Are there any hidden mechanics or something that makes them useful? Anything? Anything at all?
You ever wonder where the Fallen Empires get thier Combat Strenght from? earlier lances, now XL Slot weapons!
Lances were literally designed from the get go to be unbalanced OP. Back in that time, you could put one into every Large Slots. All lances used to be the be all, end all of weapons. PD did not mater, the enemy ships died before the fighters or missiles ever reached you.
They got reduced to the rarer XL slots to make them less broken. And the FE ships just got a 2nd one to put on all thier BB fronts, so they could once again be slightly OP in that regard. Much better solution.
That was only the time they introduced XL weapons other then the Lance.
About the DPS figures, only compare within teh Category or specific purpose:
A T2 Large Plasma gun does 9.82 DPS
A T1 Particle Lance does 20.02 DPS.
Kinetic Weapon DPS can be misleading. Even if they have armor ignorance, they still deal less damage through armor then a equal energy weapon.
Even with a DPS of 14.17 (Kinetic Artillery) to 9.82 (T2 Large Plasma), the Kinetic Artillery will loose agaisnt armor. Because that is 20% vs 90% ignorance.
Even the Gig-Cannon with it's massive damage and decent armor pen, will loose against a Particle Lance when faced with armor - because that one skips 90%.
Kinetics are good vs Shields. Energy is good vs Armor (except for a few anti-shield guns like disruptors). Missiles are just terrible.
XL slots are good vs Large and Extra Large targets (Cruiser and UP), wich tend to have massive shields and/or armor.
Also thier range is so high with 100, barely any weapon can even shoot at the same time as they.
