Why? Its a poor mans Grenade Launcher that ironically costs more than both GLs combined.
Because it is in the game.
The LAW has no purpose. So it has more damage per shot, it also has a pathetic ammo capacity. Using it against a regular mob would be a waste of ammo, using it against a tough enemy won't do as much as the M32. The only problems with the GLs smoke is when the person using has no clue *when* to use it.
Oh I totally agree, the ammo makes the weapon unplayable with the inability to carry anything else...
That being said most of the time players can easily wipe up most mobs and it becomes more of a game of who reacts fastest. If you use the LAW as a last minute super gank when a bit to much comes out at once, it is rather useful. As I say that stun effect and the reduced issue with explosive smoke makes me find that I'm better as a demo playing the LAW than I am playing the M79 or M32... but that probably explains why I never play demo
as far as leveling up for Demo... when it says deal X amount damage with Explosives to reach the next lvl, does that mean just Nades/PB's? Or does that include Grenade Launchers, too? Seems like i've been stuck at lvl3 forever.
What's with all the arguing about the LAW?
Sure it's not this best weapon for the first 10 waves, but it's a beast against the Patriarch. That's the time where most of the players use it along with some well placed pipe bombs to knock down the Patriarch's health.
