This is a list of issues that have been reported to us and will be fixed in upcoming patches. This is not a complete list of all reported issues. Issues that are still being researched are not included in this list.
So if you have run into an issue that’s not on this list, post it to the Bug Report forum and let Blizzard know!
Some bugs that may affect hunters specifically:
- Quest Items are not lootable from chest objects when their tap list is issued on creation, and the object is summoned in via a pet.
- Rank 2 of Volley has no visual particle effect.
- When a Tauren Hunter melees at a range above 5yards their bow/gun abilities on the action bar are not turning red indicating to the Hunter that he is to close to use them.
- The tooltip for the Hunter Snake Trap spell has inappropriate text in it.
