Heroes can be moved by first tapping to select them and then tapping anywhere else on the map to move them to their new location.

Different Heroes will be better in different locations. Heroes such as Stonelord are well suited to being in the thick of a group of Infantry where he can heal his allies. Other Heroes such as Eris are best positioned behind Infantry lines and away from the thick of battle, as though she may be incredibly powerful, she’s easily overwhelmed.
