Yeah, that's true. :( I'm just a really huge Greek myth nerd and I LOVE Artemis and all that jazz, and the exact same thing happened in Percy Jackson (YES, THAT MOVIE WAS VERY SRS, JUST LIKE THIS ONE) and I was sad. I still say having all the gods up there all sparkly and bitching would have made Troy even more gloriously epic, but nooooo.
(And really, I stopped caring once Mads and Nicholas Hoult died. Your version was far more entertaining.)
