Shouldn't really worry about abusive scripts like that...since you can make an abusive weapon script, class, npc, etc. Abuse is not only limited to levels.
So, taking away those levels only removes one medium for which to abuse on.
This project sounds like a good idea to get new scripters into Graal. Since scripting seems to be a dieing artform.
I would volunteer to comment on scripts, and help people,
butttttttttt I would probably end up forgetting to do so. ._. (College work makes you forgetful ;-; )
