I think the first sentence is a good one.
It is desirable that it simultaneously operates in all three modes: Standard, Wild and Classic, then there will be an additional incentive to fill the maximum stars in all three ladders every month. Only I suggest giving 5 gold per rank instead of 10 gold. In total, the maximum will be obtained in 1 month in three Ratings: 250 + 250 + 250 = 750 gold, and for a season lasting 4 months additionally up to: 3000 gold. But imagine how crazy online will be even in the seedy rating of the Classic mode? So, on one side of the scale there is a solid amount of 3,000 gold for 4 months at the maximum, on the second — an amazing online in all three Ratings.
Whether the result is commensurate with the costs incurred by the company, it is worth asking marketers about this.
