DISCUSSIONS on “Rules for online games in HoMM3 and formulas for calculating player rating.”

Unfortunately, I have to repeat myself. Regarding the Grail and the ban on it, as far as I know, this is a tribute to the Chaos rules. Personally, I don't see ANY reason to ban it in the current version of the rules. The second point is that the ban is in place to prevent players from viewing the map, and I also support trusting online players. What else? Is the Grail overpowered? No. So why ban it?
