Artyom, you do it very simply. Since you've taken on hosting CIS-2016 in St. Petersburg - pressure Baratorch (if necessary, we can donate a bit) regarding the creation of an "experimental" version of SoD with one single global change - "rebuilding the Mage Guild based on the VT principle." Then announce that CIS-2016 will be held exclusively on this version. Period. And don't explain or prove anything to anyone. History itself will judge who was right.
