Snap firing mode makes a lot more sense for a GL than a RL, so I wouldn't worry that much. A bigger problem is that the GL's innate stats are insanely good; basically it's the same as a small rocket, but waaay more handy (lighter, smaller, faster and more accurate), not to mention it has ballistic profile (which in most cases is an advantage).
I spoke with
Dioxine earlier and after some deliberation we nerfed GL's power and made its ammo heavier (they were lighter than anything else in the game.
) After the changes the GL is still useful, but not so much of a game breaker.
Having said that, this is an excellent mod that should have been made. We just polished it a little, as it seemed unfinished.
A suggestion of the new ruleset is attached below.
