(doesn't seem to be many threads about the Siren... or so a search on Siren gave)
I know the Siren already has a decent ability to destroy explosives in her scream radius, but all I've ever noticed is she gets close to players before screaming, which isn't too effective at the grenade disintegration part of her ability.
So, what I propose is to have an additional time for her to scream. When a demo fires a grenade, or just any player throws a grenade (incendiary or explosive grenade) and it's in her scream radius, she'll immediately try to scream and disintegrate the projectile. While this would seem to be pretty useless overall, it certainly gives her some extra survivability against a Demo, and also a side effect. Obviously if she's in a crowd when this happens, she basically just protected the crowd from obliteration.
So in essence, this would turn the Siren into something of an explosives defense for the Specimens. The only real problem with this is a probable need to increase her scream radius due to the speed of the M79/M32 grenades. That, or she could simply start a scream while the projectile is in a bit larger radius than her scream is, just to give something of a preemptive anti-projectile scream.
