Kun-Lai Runt - This pet has an amazing 1-2-3 punch to knock out your opponents. Start with Frost Shock to apply the Chilled debuff. Next cool your opponent off even more with Deep Freeze. Follow up with a Takedown to hit your opponent for a massive amount.

I used the one I got before 15 minutes was up, but it sounds like you need to open a ticket.

Just want to 2nd the Grizzly Hills idea. Same pet, higher starting level.
