Changes to the rules starting with the letter G (Graal and Galtran).

You should rather think about the fact that taking screenshots during map/air view should be considered a violation of the rules. Since the cost of one unit implies that, firstly, it is possible to do this every turn, and, secondly, the spell can only be cast during your turn (and not during the opponent's turn, essentially using this spell). There were complaints against Sanya in the CIS community for blatantly creating models of upcoming battles in the editor. In my opinion, these are all manifestations of the same problem.
Also, banning the guard calculator is exactly what is called a third-party program that allows you to influence the game process. And there is no need to talk nonsense and compare it to a regular calculator...
And those who will sing songs about how it is impossible to track this in any way – well, it is almost impossible to track stream sniping. In any case, almost everything in Heroes is based on trust. You just need the will...
Or maybe the Grail got in their way... 5x5 is 25 cells, just so you know. And if you are unlucky with the terrain (open area - which happens all the time), then you need to spend 4-5 days digging (and this is if you dig with 4-5 heroes, and not two, and even near the city, so that you can recruit new ones). 4-5 days of lost tempo. 4-5 days without full-fledged chains, and the opponent will eat a couple of treasures and arrive with a red ball and 30 stats. The Grail is definitely the same component of the game as any other. And this component requires assessing the risks in each specific game situation. It is obvious that something needs to be done to fix the bonuses of individual cities. But, I repeat, the problem is solved very simply - remove these bonuses altogether, leaving only the growth and +5k. Or, we only place the Grail in the starting city - and then this will be an additional component in the auction.
