9. “Move It”
The little black thing next to the keyboard is called a mouse, and it should be used carefully, especially during boss fights. Also in Heroes of the Storm, a little movement is required of you. Of course, not as much as in a dungeon like World of Warcraft, but you shouldn’t take every hit.
The bosses all have a large AoE stun that deals significant damage and a smaller AoE that roots you. You should avoid both attacks whenever possible to avoid participating in the fight with unnecessarily low health in the event of an enemy gank.
Likewise, you should not neglect your mount. Longer distances don’t need to be covered on foot, but can be comfortably and efficiently traversed while mounted.
