unlike the laser cannon vs proton cannon issue this one is much more clearcut (go read that thread if you don't know what im talking about okay???). hee hee
laser turrets and proton turrets both have the same reload. laser turrets do 10 damage against shields, 0 against armor. proton turrets do 10 against shields, 10 against armor.
applying the armor damage = (AD + (SD/4)) and shield damage = (SD + (AD/4)) we get:
laser turret: 10 shield damage, 2.5 armor damage
proton turret: 12.5 shield damage, 12.5 armor damage.
so the proton turret is 25% more effective against shields, and 500% (!!! hee hee ;)) more effective against armor. five hundred percent!!!
but wait, you say, being young and ignorant (hee hee just kidding hee hee ;)).. what about the range? laser turrets have 235012823085 times more range than proton turrets, right??? nope!!! both types of shots have the same duration, but the lasers fire slightly faster (875 vs 850), giving them slightly greater total distance covered before they expire: a grand total of about 3%. maybe it is a little more because the lasers have a longer graphic and EV may be a bit lazy in its collision detection and mask checking (i'll ask matt sometime. hee hee ;)), but i would say at most they have a 5-6% longer effective range. this really should not matter unless you are doing something very cheesy like monty pythoning all over the place because you have no skill and can not beat EVs simple AI without being super cheap. you aren't monty pythoning all over the place, are you? even if you are, 5% should not compensate for five hundred percent greater effectivness against armor that the protons would give you.
really the only thing that laser turrets have going for them is that they take up less space, but since they are soooo bad at killing armor, youd probably be better off buying, for instance, 2 proton turrets (60 tons) instead of 3 laser turrets (also 60 tons). you'd lose about 25% of your efficiency against shields, but gain 300% efficiency against armor, which is probably a worthwhile tradeoff even with EV's shield-heavy ships. plus, proton turrets are blue (i love blue hee hee ;)) and do not have the yucky laser sound, so my vote goes to proton turrets!!!!!!!!!! hee hee
