What we need is tracking .. lots and lots of tracking. All crystals should have a tracking bonus so that we have the option of sacrificing dps for the ability to actually apply dps (ie. same as is done with projectile ammo) ..

I would argue YES, but I don't. Here's why:

Through recent changes and advancements, only about 60% of Amarr ships are incapable of doing other damage types. Why 60%? Because the other 40% have been given large drone bays, launcher hardpoints, and in many cases, simply no weapon bonus at all, making the use of autocannons and artillery far better an option.

We've been granted the ability to diversify quite well. Adding more versatility in our damage capabilities at this point would almost completely throw the developer reasoning for converting so many Amarr assets into amalgamations of Gallente or Caldari ships, that it would create fire and brimstone on a threadpocalypse level.

I'm a huge Amarr fan, but giving them variable dmg types would be the weapon system far to powerful imo. I do think however some the Mattari T2 EM resists are some what extreme.

Lasers are already the 2nd best weapon system in game overall. And exp lasers are harder to explain lore wise.

Hybrids should be the ones getting dmg variations. They could use a boost, and not only would it be easy to explain lore wise, it's hard to explain why different element hybrid ammos don't already do different dmg types.

A great weapon system on paper, which significantly penalizes the usefulness of the ship when used, and cannot be reasonably be fitted on ships that don't receive specific bonuses to do so.

Hybrids are used by two races which each have options for completing their damage portfolio. They aren't exactly hindered, especially since hybrid damage types specifically address shields and armor in turn, and caldari missiles and gallente drones receive far more boosts within their race than, say, Amarr.

All in all, I'm feeling it's kind of balanced around here, though I predict an equally large threadnought if Amarr were left as the only two-damage primary weapon system.

I have a Idea to Address the lack of damage variation to the laser weapons.

Mining lasers use a tunneling laser to bore into rock and a tractor system that draws in the raw materials.

reverse this Idea, make laser crystals with metal cores that when the laser is fired it strips the core material and strikes the target with alternate forms of damage (I.E. Lead, Iron and Tungsten do Kinetic. Uranium,plutonium do explosive) allowing variation to which weapon damage type works best against the target.

Also these Metal cored crystals have a limited Lifespan of shots as with each shot they strip more and more of the core material with each shot. Thus making them "Ammo" limited weapons.

Such "Core" crystals could be easily added to the game as blueprints that us crystals and the needed rail/blaster ammo to manufacture them. Display wise adding off color motes into the laser stream should make note that this is a "Core" crystal in use.

While we're at it, let's give blasters and railguns ammo types that do different kinds of damage. Let's cut the DPS of blasters a bit, give them really, really good falloff too, and then call them "Autocannons".

Also, we should consider giving Railguns a massive increase in volley damage while basically throwing their rate of fire into the toilet, and also cutting down their range somewhat.

I think this new and incredibly powerful weapon system should be christened "Artillery".

Lets give the already frighteningly op pulse lasers choice of damage (which they can instantly change) as well, what can possibly go wrong?

Truth is limited damage types only matters at all if your enemy knows what you are going to be fielding, and if your enemy knows what you will be fielding you have worse problems than damage types. Normal fits are all omni tanked so whether you have em/therm lasers or kin/therm hybrids is largely irrelevant. The damage adaptability of projectiles is massively overestimated (it doesn't exist on t2 ammo and even with t1 ammo it only allows for partial coverage often with 3 damage types meaning you are always doing one of the worst damage types as well). Only missiles allow for true damage type choice and they are limited in plenty other ways.

You can easily say the same about T2 Amarr Resists, a Vengeance with a damage control, one adaptive nano plating and level 5 assault ship skill has, 74.2% EM, 66.5% Thermal, 80.7% Kinetic and 89.7% Explovive resistance. So if Minmatar T2 have high EM and Thermal resistance I think it is completely balanced.

The main thing to happen with crystals is give us a choice between EM heavy or Thermal heavy. While the T2 Crystals can (& I think are) semi balanced between the two.

This can be done easily by removing the 25% range steps... This then gives us 6 kinds of T1 Ammo, 2 at +50%/0/-50% which lets us choose EM or Therm heavy damage. Giving us a little flexibility, especially at long range where Amarr only do EM damage pretty much on the T1 crystals.

Did the legwork using current numbers
New and improved;
T2 crystals as is.
Heatsink RoF modifier changed to damage ditto, for T2 make it 22.5% damage which is 0.4% dps decrease .. small (maybe too small) price to pay.

Multifrequency: 36 EM, 12 TH. -50% optimal range.
Gamma: 36 TH, 12 EM. -50% optimal range.

Xray: 24 EM, 12 TH. +20% tracking.
Ultraviolet: 24 TH, 12 EM. +20% tracking.

Standard: 24 EM, 12 TH. 25% reduced capacitor need (note: This is only half the bonus present on hybrid ammo!)
Infrared: 24 TH, 12 EM. 25% reduced capacitor need. (note: This is only half the bonus present on hybrid ammo!)

Microwave: 15 TH, 5 EM. +60% optimal range. +5% tracking.
Radio: 15 EM, 5 TH. +60% optimal range. +5% tracking.

Four groups each both EM and Thermal represented, divided into three range bands with the middle having twin flavours of tracking and sustainability.

...You could simply give T2 Ammo the possibility to absorb overheat damage. So its useful and needed in high amounts :D
You could choose to do 5% more Damage for using T2 or 20% more for X seconds...
