Hmmm.... after messing with this new system, I'm not sure I like it too much.
The reason: Some of these weapons can be *very* powerful. And if all you have to do is go sit in a corner for a bit before you fire it again, you can exploit the heck out of pretty much all of them. Even if they take a huge amount of energy to fire.
I was experimenting with doing that very thing, and it is indeed exploitable very easily in most situations.
This also was causing me to not use missiles unless necessary, because they arent needed in combat anymore.
Also absolutely wrecks the damage VS enemy HP balance of the game.
