Long range isn't bad either...they offer different trade-offs is all.
- Both extend range while reducing damage/DPS, and both actually have higher damage and DPS since their damage falloff range gets longer too. Even down to 1k range, you'll notice the damage increase.
- Focused get the added bonus of increased armor penetration, but they also fire slower and generate a lot more heat.
- Long Range are heavier, draw more power, and use more distributor per shot, but they maintain the same fire rate and they don't run any hotter.
Many people are claiming that focused is categorically better than long range, but the truth is more nuanced. Focused are better once shields are down, but they don't bring shields down as quickly due to their reduced fire rate, and their additional heat output could easily cause problems if you're already running hot mods (like dirty drives and/or overcharged plants, both of which are extremely popular). Long range technically drain power faster, but they also shoot faster and retain the high heat efficiency associated with pulse lasers.
Each has their uses. Pythons can run either, since you could pair focused with an A7 low emissions plant that will counter the added heat of the weapons fire, or you could pair long range with an A6 overcharged plant that will accomodate their increased draw while also increasing your agility (A6 is 20 tons lighter than A7, which yields a slight but noticeable bonus to ship handling). A Vulture, on the other hand, will probably need to run clean drives if you're going to also run focused, since it's almost certainly running an overcharged plant to mitigate its power management issues.
