No reason to go out of your way to be rude, my bluntness is not personal. But these sorts of scenarios lead to endless arguments in game. And you are incorrect in your assessment. But I have refused to do wars in about 4 years based on the endless arguing that ensues from RP rules that are supposed to be applied without any sort of moderative authority. And I'll assume you have opened tickets based on your experiences with the magic system in the bugtracker.
Additionally, the banning of magic and potions
do not eliminate imbalances from dueling. The list of possible glitches or exploits is technically unknown. It is interesting that the Sapere Magi lost the war with the Outlaws, and then it was Eid that dropped the tria and silverweave all over the world. Why do you think he did that, but
didn't use that knowlege to win the war? Because certain players at that time had knowledge of exploits that led to an unfair advantage in duels, amongst other things.
Many of the exploits that have been fixed in the past would have given an unfair advantage to dueling, but would not have been necessarily related to magic or potion use during dueling. You might as well have a rule that only characters created since .5 was released can only be involved in the war, since you are probably going to be playing or fighting against characters that have taken advantage of exploits in the past.
Since you can cast magic now only while remaining still, and potions are heavy, then it should be a proper war. Attempting to enforce some sort of behavior where they can't use potions or magic, but any glitches related to weapontry, training, movement, inventory, and progression are perfectly allowable is laughable. Use the system as it is, provide feedback in a proper manner if something does not work correctly and then let it go.
And if it is to be a proper RP war, who will moderate and according to what rules? A bit OT, but the ruleset for Ars Magica 4th Edition was released for free recently. I'll go ahead and add the link here, as I think a few would find it to be an interesting read. Ars Magica is the system that PlaneShift (the RP, not the mechanics) reminded me of when I first found the RP community in PS, so I thought it was worth mentioning.
