I wonder how players with hundreds of heroes manage all those heroes.
Going further, I would recommend the exact same ability to sort through heroes in the Castle -> Leader tab to show only the heroes currently in that city.
I also would like to see the ability to click on a hero in the Attack screen and get to the hero page where I can activate/move artifacts. Many times I select my troops to send somewhere, find out that they are taking a long time to get there, so I use one of those speeding (logistics) artifact, and have to reselect all my troops again to send. Very tedious.
And how about the ability to transfer artifacts amongst all heroes in the same group WHILE in transit to somewhere?
And when a hero dies, a dead hero timer in the tavern/church for the hero to disappear from rehiring/resurrecting would be extremely helpful.
In short, I would wholeheartedly welcome ANY improvements that would ease our hero management.
