Are you getting an early combustion in during air phase? It looks like you are from logs due to your spike in damage around 21:24 but I can't tell for sure.

You actually want to pop your CD's at the start of the burn phase, not just before you combustion. The only things that go up last moment before combustion are LvB and Beserking if you are a troll.
