It only ups crit chance for snipers. But in snipers every tech tier ups the crit chance.

Well, they were able to destroy brick walls. So they're fairly powerful. So I'm going to assume they're around 1000 degrees Celcius, with the power to melt through a steel wall.

It has a positive charge because of the lack of electrons. Electrons carry a negative charge, protons carry a positive charge. It's quite literally LESS electrical than almost any other form of matter, because all the electricity has left. This is also what makes it superconductive and susceptible to electromagnetism.

As I said, plasma can move as fast as the force affecting it propels it. And while we can relatively easily create plasma, launching it at an appreciable speed is a problem. We could build plasma weaponry, the plasma would simply dissipate rapidly after leaving the barrel, move slowly, and have less destructive force than modern ballistic weaponry.

Also, don't say 'literally' when describing something physically impossible.
