t seems to me that they will now persist through log outs, dungeonqueues, BG queues, deaths of a variety of reasons, and summons. This is very neat, now I won't be without a companion again.
Companion pets will now survive:
- Log outs
- Dungeonfinder teleports
- Deaths from a variety of reasons
- Summons from warlocks
- Mage teleports/portals
- Flight paths
- Arenas, though they still won't be in the actual arena during combat
- Battlegrounds, and they will join you during the combat.
