FFXIV FL Win Log: Ice Map (Don't do this)

I made a mistake here at the end. I got confident that we could wipe one team, and have enough firepower to wipe the second team coming from our flank.
As you can see in this video, it didn't work. Rarely, does it. When you're close to winning and you have a big ice, you will be double-teamed. Going for middle after killing blue at 14:19 would have been the best choice to not only corner red by tailing them, but also, red chasing blue out of our crystal.
