I voted 4:
1. Set Effects enabled. I know some pvpers were farming and spent tons of gold for the eternal flame set, but useless in the tournament. Also, set effects boosts different classes by different amounts.
2. Deviation between Forest and City. Gives more choice to the pvpers. People have different playstyles.
3. Keep it in Balanced. Though its in Free Mode in Klunia, the upcoming patch for balanced will make it more fair.
4. Body Trap. Depending on if it is banned in Klunia. <- Need clarification
5. Lift the limit on windmill and input a limit like no more than two windmills at wall. Windmill is mostly for show and the user risks him/herself when using it. <-- This isn't really needed, but I doubt it will hurt the future tournament.
