You know Quiet; one damn good idea for a mod would be a Rocket Arena 3 type vote system mod.
If you have never played it, you can call a vote to disable certain weapons, fall damage, team damage, whatever.
If given the options, players in this case could do that to disable certain guns, Force powers and so on.
You would think this vote system is abused with a call vote every 10 seconds, but it is not.
It's all GUI, very similar to the vote system in JO now, no console knowledge is needed.
