Please consider to implement batch hiring mechanics
Prerequisites: At this moment heroes hiring needs 5 clicks + 2 click to check his skills and fire him
And when player rolling hero with specific skills, let say Warlock with toxic cloud on second slot it can take some hundreds attempts
Multiply some hundreds attempts on 7 clicks and you will have hours of useless pain
Have it to be part of gameplay?
Suggestion:
Create interface to make 10 or 50 hire attempts by one click by price quantity*character_hiring_price
After rolling player can choose 1 and 2 slot skills from randomly rolled skills
This mechanics will save time and mental health of players and made them happy


will allowed you to pick any skills you wanted
