It is being said more often now by those who have level 40 heroes that it is too easy to get 2 stars now. I think a possible solution would involve changing the battle/star reward system. Currently you only need get 50% to get one star and destroying the TH gets you a second star.
What if instead of having to get 50%, you had to get 60% or 70% and so on. Obviously this throws a chink into the game, but I think it could be according to league level. So this update may only really apply to the champions and masters leagues.
UPDATED:
Maybe there would be some sort of incentive along with the fix to the star system.
1. You could update the league bonus loot system. This way it helps make people want to go to a higher league
2. You could also provide a higher bonus if you got 60% 70% and so on
3. change the 3 star system to a 5 star system where 1 star is destroying the HT, two stars for 50% 3 stars for 75%, 4 stars for 90%, and 5 stars for 100%
of course that means that you would have to divide up the trophy allocation too
ex. 30 available trophies
1 star = 6 trophies
2 stars = 12 trophies
and so on
5 stars = 30 trophies
This is a very rough idea but tell me what you think
