Here is some general rationale for not mixing guns.
- Don't mix gun types.
- Put as much firepower on a target as fast as you can.
- Keep the target in your optimals.
- Do the damage that the enemy is most vunerable to.
- Keep transversal velocity of your target low for damage, high for defense.
- And finally, be ready to switch ammo to compensate for targets that you can't catch, or get in too close.
Most people mix guns for the purpose of staggering ranges, which means at any given time, several of your guns aren't firing. Wrong. You neen ALL guns putting damage out ALL the time so that you maximize the damage you do with EVERY shot against a SINGLE target.
You want to get as many hits on a target as quickly as possible for the most damage you can. By mixing gun types, you're adding time it takes to kill the target--which is more time for your enemy to try and kill you.
Pick the best set of one gun type you can mount and put that on your ship. Maneuver your ship to keep yourself in those gun's optimal range. If the enemy gets too close or too far and you can't catch them, switch your crystals/ammo to compensate. Same goes when you're heading into a fight--if you've got 40 clicks between you and enemy, load up radios, fire your weapons, and then switch to gammas or multifreqs when you're within 10. Put as much firepower on your target in the shortest time you can.
Ship-to-ship combat encounters in EVE are measured in seconds or minutes. And the differences between a ship's damage output or it's armor or shields resistances is measured in single percents. People pay millions for modules and implants that do 2% better.
So if you're flying around with 6 turrets, and you've got two turrets firing at frigates, two turrets firing at cruisers, and two turrets firing at the battleship, you'll do absolutely nothing against any reasonable enemy pilot. Rats of course are a different story, but we're talking about PVP here.
Other games are programmed to allow the player to mix guns effectively. SFC3 was such a game--you were limited by the slot type to the size of the gun; on one ship, you could have 6 turrets but only 4 could fit large guns; the other two could only fit small "point defense" type guns. One strategy, called the Alpha Strike, called for the player to close on the enemy and fire all guns. But SFC didn't model optimal and fall-off ranges effectively, and it insisted on much longer recharge times for its weapons. Battles could go on for hours.
Not EVE. With one of the main measurements of a successful generic combat ship being DPS, you simply cannot afford to do anything but focus your fire effectively against your enemy.

Pick the best set of one gun type you can mount and put that on your ship. Maneuver your ship to keep yourself in those gun's optimal range. If the enemy--or the rat-- gets too close or too far and you can't catch them, switch your ammo to compensate. Same goes when you\'re heading into a fight--if you've got 40 clicks between you and target, load up radios, fire your weapons, and then switch to gammas or
multifreqs (for example) when you\'re within 10. Put as much firepower on your target in the shortest time you can.
Don't mix gun types. Put as much firepower on a target as fast as you can. Keep the target in your
optimals. Do the damage that the enemy is most
vulnerable to. Keep
transversal velocity of your target low for damage, high for defense. Get that one? And finally, be ready to switch ammo to compensate for targets that you can 't catch, or get in too close.
Decide on the right gun for the job and stick with that gun. If you want a change in range, change ammo, not the gun. Or fly your ship to (or away) from that target. Your goal in combat (
PVE or
PVP) is to focus on a target and kill it, then move to another target and kill it. Bring every gun you have to bear on your target at all times. If you don't, you are wasting potential and increasing your chances of death. To people who say, "but how do i get targets that stay outside my range" I say, "fit long-range ammo" ... oh, and FLY your ship instead of click-orbit at 10km.
