Well it is a script that makes something a bit more simple... but it's like using different crosshairs... it might make things a bit easier but it doesn't really affect gameplay much. Comming from Tribes2 where everyone uses scripts and where it is allowed I use the same logic as pure servers do there. Anything that doesn't affect gameplay directly to give you an edge is allowed... this could be enhancements like crosshairs, change of FOV etc.
Tribes2 is built with scripts in mind so the server can actually disallow scripts that do not follow these rules... I wish all games were built like Tribes2... no cheaters there
