I'm currently having trouble doing any significant damage in the HAAT. I can solo the Rancor raid with a CLS team and I can solo P1 if I can force myself to pay attention to the rage timer (xD). But for P2-4 I'm having trouble doing anything worth noting, with my Rebels in P2 I might get around 800-1000k or something, but that's it. In total I got 2,4 mil in the last HAAT.
I've been looking at HAAT guides (http://petebutler.co.uk/mrpi/
but there's just so many teams possible that I can't decide which would be best to focus on building in the long run.
These are my characters, and I'd love some pointers as what would be most efficient to focus on https://swgoh.gg/u/angeloonie/collection/
