Legend III is perfect as it is, as a semi casual player can get in to earn the max Star bonus And to be in the highest League .
For Legend II , I should be for the active players who can play competitively but don't want the Hardest modifiers
It Should be a step Up from the Legend III, So I think it should Have 4 Daily Attacks as a weekly tournament that is , Monday being the sign up period then Tuesday through Sunday and the Top 3 people should be promoted to Legend I , Instead of the 30 weekly attacks as those can be completed with one clan castle cake and 1-2 hrs of free time .
Thus Legend III can be for casuals , Legend II for the Wannabe Competitive people , And Legend I for the Actual Competitive people
(Only Legend I will be negative trophy and Legend II&III Will have positive only)
