Classic Stuck in combat Horrific Vision Orgrimmar. Plz hlp!

So i have had 2 keys wasted this week because i get stuck in combat in Valley of Wisdom. First time i was half way through clearing the zone, killed first mini boss, and wanted to Orb before pulling next group. Couldnt do it. Wasnt engaged with anything. Panicked, attacked the next group and died while panicking.2nd time was today. Cleared Valley of Wisdom, was heading to Thrall and went to Orb before engaging him. Couldnt do it, and lost right there.Is there a mob that im not aware of in VoW that keeps you locked in combat, even when out of range? via /r/wow https://ift.tt/2uQNdJu
