I was posting about the details of the issue you started as the OP. I didn't say that any of those factors should / should not be used. However, they are factual elements of the various energy weapons, so they are important to consider (see below). As far as what is needed, I only stated that EVE visual effects need to be included, or something similar, since modders already showed how to do so (and they really were needed compared to the effects projectiles were given). Since you bring up the subject, let me be explicit about what is needed as far as my points are concerned.
Your subjective preference for what would make a good implementation of energy weapons is only yours, not all player's. It is totally untrue that an invisible, recoil-less, soundless energy weapon is a terrible idea. Obviously you can see if you hit or not because you would still see the effect (as I mentioned, this is what occurs with such energy beams in real life). It would be far more satisfying to use than weapons that make no sense / violate actual principles of such weapons.
Why do you think you can see bullet streaks? Because you can actually see bullet trails in real life in many instances, obviously.
For many players, particularly players who want to role play intelligent, tech-oriented characters, using energy weapons that violate actual behavior / physics of their claimed energy forms is immersion-breaking. For example, there was a reply above about the silliness of claiming that there is a "cryogenic laser". There is no such thing and never could be because of what a laser is and how it works (hint: "laser" is simply an acronym that was accepted as a word once it became well-known, and originally simply meant "Light Amplification by Stimulated Emission of Radiation" ... which is why a "freezing laser" makes no sense at all since freezing anything removes energy). It might be feasible to somehow make a device that removes heat from a target and freezes it, but it wouldn't be a laser.
Anyway, the point I was making is that energy weapons need to be believable and thus need to be based on their actual energy properties. Otherwise, the lack of basis in actual physics makes it very hard to attempt to role play characters who specialize in such weapons and and related technologies.
So yes, the various points I made, or most of them, need to be included in order to effectively role play an energy weapons, tech-oriented type of character concept. Or there needs to be some explanation offered (i.e., lore you can find) regarding why the techs work as they do rather than as we currently understand such physics.
