Wait wut?! I thought ballistics did hull damage and energy did shield? I'm so out of the loop, lol. I do know that with distortion cannons though, I would certainly want my chin gun to have a bit more of a fire rate then the M7. Although the M7 pairs beautifully with the BVRS ballistic gats.
Sorry for late reply, most people have chipped in already but to put my tuppence on display:
To my knowledge here are the rock paper scissors of it right now:
Ballistics bypass a bit of shields, but need to work on the armour. They start damaging right away, but need to do a bunch of damage.
Distortion strip shields fast and damage components without hitting the hull at all, but you need to target the components or you'll miss them.
Energy weapons include Laser, Plasma and Neutron. These do shield damage and whoooole lot of hull damage, but you need to drop a shield face first.
The benefit of Ballistic is low-signature and bypass a bit of shielding. The drawback is they need to be replenished.
The benefit of distortion is you can strip shields and disable ships systems without damaging the ship hull. Lots of opportunity for no-kill play with these, but as far as I am aware the component damage part of them doesn't work yet.
The benefit of energy is they are the scissors to armours paper, and that they are infinite as long as your jiuce keeps up with your trigger finger. The deawback is so are the shields so if the foe can keep you off their back for long enough they will remain wrapped in plastic.
Bonus: EMP, an area of effect hit for short term disable and shutsdown of ships systems, but it hits everything so a tool for loners or friends who think they smell.
As far as I know, this is as it stands right now. Balance and more weapon types added to the game later may change the above, if it isn't different already!
