I find it annoying when I want to boost my Heroe’s along with my troop/spell production that I have to go around the map and boost them 1 by 1 when using spells. There’s already a button when I select the barracks or spell factory to boost each of these items, finish troop training/ spells and heal the Heroe’s all in one convenient place. But there’s no option to boost the heroes!
That would be appear to be a relatively easy & appreciated upgrade.
Thanks for listening and hopefully you’ll add it next update!
