Often times you'll see a spawner die instantly but 30+ people used cripple spawner on it. I suggest creating a random range such as 90-100. There will still be overlap, but perhaps it'll make usage more efficient over time. Same with napalm and nuke and clusterbomb.

Maybe have it a "High activity" toggle.

Not sure if this is possible but maybe create an irc channel for automatically coordinating abilities via the script.
