The skill of digging for the Grail has absolutely no bearing on the game.
Actually, we played an unforgettable series with Twaryna, where you could start digging for it from the first week. Ask him how many times the Grail was ultimately placed?
If we're talking about sportsmanship, then we should eliminate cons, hives, and utopias (because one player places 4 cons one after another on respawn, while the other has a couple of mini-hives; one player gets control in utopia, while the other gets a collection of sea creatures).
