I was Janna, with a little more than half health. My adc had gone back, and it was just me protecting our tower. Then the hecarim jungler dives me as well as the sona and cait (lucky neither of them had their ults). I pop my ult, pushing them back, and they still try to dive me again. Cait is now taking tower aggro, and I keep hec off me with my tornado and by flashing. Cait dies, and sona is taking heavy damage from minion aggro ass hec is tanking the tower. I slow him and dance around him, keeping my shield on me. He dies. Then sona dies.
Yes, triple kill support Janna ftw.
