Several days of excavation – that’s a loss of tempo, and that’s what’s really annoying. Or do you send all 8 heroes, led by the chieftain, to excavate? It’s like an archaeological expedition. And then the opponent shows up on day 7, it’s the same thing.

In general, the Grail makes sense to allow only on large, variable maps with a large number of zones.
And on such maps, the two heroes you sent to excavate will slow down the map processing by 15-25 percent.
It takes two days to excavate one Grail – to stand on the cell, then to dig: on average, you will dig, taking into account the radius of the crosshair from the center of the screen – about 10 days with two heroes. And then you still have to transport it...
So, do the math, accountant...

And here’s another important point about the Grail. The only case when it should not be possible to excavate it at all is if it is buried on the starting location of one of the players.
