With Territorial Instincts talent you could use Intimidation without having active pet summoned. It would just summon my cat to stun the target. Now it doesn’t do anything in battleground after last Wednesday patch
Edit:
They’ve change behaviour of Territorial Instincts in 11.0.2. Instead of summoning a pet from hunter’s stables as tooltip for the talent says, it tries to summon some neutral or friently creature from the area.
In battlegrounds there are no creatures so it just uses the cooldown and does nothing…
