I would still prefer to pick rules systems for PVP on a case-by-case basis, which econ quoted as the current draft rules. There seems to be a trade off between the speed with which the war is resolved the and the control players have over the armies. LotR rules should work fine for wars between adjacent provinces, and we can move toward faster rulesets as distances warrant. If we work out what these rulesets are before hand I don't think it will be a big deal to decide which to use on a case-by-case basis. Finally, this would allow us to test a variety of rule sets, and I think more testing is something our PVP could really use.
