you should try to use bukkit++, I was using it to try and reduce lag on my server and spammed scatter and nukes, seems to work pretty well
here read this: http://forums.technicpack.net/threads/cb-upgrading-tekkit-3-1-2.19176/special attention to this line: Build 76 seems to not work, please try build 75 instead!build 76 starts ok but gives some erros with time, specially bad port errors
but if anyone knows how to disable specific modes please tell us! It would be useful to disable scatter just because it wrecks the landscape!
