skull supreme

idk why 9 heroes with full troops VS 1 hero with 0 troops need nearly 100k skull for supreme only because he have 20 heroes fighting 26 heroes of my army nearby 
my point is when a heroes are fighting in a land shouldn’t give skull supreme to other nearby heroes until their battel ends
how can you help some one while you are fighting in somewhere else ?!

You can only be in 2 differents battles if you r tower gard.

The battle have no impact on each other, what matters is : tile properties , troops , players involved and research bonuses.

And also it is nearly impossible to achive supreme victory rright at the beginning of a battle.
