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

Most people haven't expressed a unified opinion. For example, I haven't heard a single argument why the Grail should be banned. Someone takes Wings for a horde of wood, someone gets 3 Griffin Conservatories for 9 Angels at their native respawn, and someone digs for the Grail. Why not? Why make the game poorer? I don't think the Grail introduces any huge imbalance into the game, especially on a resource where many play on a SM (small) map, on which there has never been balance. If the problem is about trust, then I don't see a problem at all :) : don't play with those you don't trust, and that's that.
There are, however, towns in which building the Grail gives a huge advantage (Tower and Conflux), so building it can be banned in those. In the others, besides 5k per day and +50% growth, the bonuses are fairly insignificant. And with the Soda bug, you can easily peek at the town's income; you'll need not only to dig up the Grail, but also to hold the town in order to extract profit from it. In short, it's a fresh vein in the game; I think it should be tried out for at least 1 season.
