New arena build

I've been using a Sith team for a while now (which I know isn't viable anymore) and routinely get my butt handed to me. I'm hoping for some assistance with building a new team. I've got a good variety of people, so farming one or two new characters to make the perfect team shouldn't be too big of an issue as I'm also lite P2P.

Additionally, any fleet advice is welcome, though I don't struggle as much there. Thanks!
