pro league is undoubtedly a unique mode. It usually offers all the players to play with a fixed attack combo of spells troops and pal against 12 different bases ( each bases are different , mostly the toughness increases from 1 to 12 )
I want to suggest something
Can we have pro leagues having same base but 12 different combos for 12 attack.
I think it will be intresting. That will become something totally new. And on announcement u guys can put the base map. I am sure players will like the challenges.
