I read that. It's just a downright stupid option, in both games.
How would such a weapon simply disintegrate? And even if it did, it would still be recoverable easy enough for qualified engineers. Unless it crumbled to microscopic pieces, which seems unrealistic on so many levels. (Just think on how much energy would be emitted, especially if you decompose Elerium too.)
You've obviously never actually seen the plasma pistol break up when you kill a Sectoid in the remake, nor have you seen any Star Trek episodes with the Hand Phaser set on Overload or even consider how much energy is involve to fire a bolt of energy through the air without losing integrity.
It's actually very easy to imagine a self destruct or even a malfunction, being the cause of an energy weapon to be destroyed. The present Ak-47s have already proven to be able to have catastrophic failures and explode by detonating the magazine, leaving only the barrel and the mangled rear half of the receiver, pistol grip, stock and deceased user.
Also, you've never played the remake, or you would know that the plasma weapons there do not disintegrate, they leave 'Weapon fragments' which are in fact used to study weapon research, including the human laser technology. I will always remember this because I was always lacking 'Weapon fragments' for research, was too good at capturing the whole intact weapon and users.... >_<
So clearly, what you people want is exactly what is presented in the remake, but how will you go about it? >_< Even if we could program 'Weapon fragments' into the game, how will you calculate it?
A heavy plasma leaves 6 pieces, a rifle 4 and a pistol one or two, how work will it be to program how much each weapon will leave behind after their destruction? A cheap easy way will be to program a random number of fragments you will get at the end of each engagement, but it will be an inaccurate count if everyone is okay with that.
Also, how would research be affected, can it be programed such that a certain amount of fragments is required to research each subject like the Remake. I haven't tried messing with the research trees yet so I wouldn't know >_<
I suppose another cheap easy thing to do is to program the manufacturing of the laser weapons will require a certain amount of 'weapon fragments' for the pistol, rifle, and heavy laser. The cannon may require less because it's huge, maybe more human tech is in it than a compact handheld Laser. This idea will only work if the earlier idea of 'random fragments acquired' is implemented, otherwise there will be no other way to acquire weapon fragments.
Seems like an awful amount of work, still, if you choose to spend your 'Weapons fragments' from early game encounters on Laser Research first, it will significantly delay plasma weapons reaching your men in the field.
Personally, why not just make laser weapons require alien alloys or something >_< why do you people want them to appear so late, things will really start to suck when snakemen onwards start to appear >_<
