Thanks for the video, nice strategy. I may give this a try in legends a bit.
First attack, seemed like the hogs were a little late. If you release as soon as you know the GT is going down, the BK might have been saved.
Second attack seems like a good showcase for bringing one EQ to trigger the GT so that the hogs could hit it right away. It was basically luck that the hogs + warden were in the area when it activated. We've probably all seen attacks where the warden decides to follow a group that doesn't go to the GT, and then the GT destroys the troops piecemeal.
