mrmcgee posted one a week ago, as well. I like your movement keys. Your phase 2 was so much more controlled than mine is, but eh I make it through so really have no reason to change.

Oh and one note, you can stun the champions. Reduces your tanks incoming damage a lot when one of them isnt attacking for 7 secs. It's on diminishing returns, like pvp, so only use the stun once on each one and you get full duration. Makes that first fight so easy.
