What is the issue with a single GM controlled stat? I've run two WiRs respectively and those are entirely based on Stats run by the GM >.>

It's a lack of creative control and the wide window for fabrication by the GM or the co-GMs to suit their own course of the RP since there's no on-sight program to track things like rolls or determine anything that couldn't otherwise be fabricated in the process of reading, interpretation, and assigning values for calculations. It's an undue complexity better suited for a simulation specefically designed or built to run these calculations on the spot with minimal human intervention.

If it must be done by a person, it's better run in a physical environment and where all equations are out and in the open for all players to check as they go and to keep a environment where everyone can keep the other in check.
