What up guys.
I got back to playing through this recently on the Xbox (actually doing it backwards compatible 360 which is laggy as crap but whatever), and the influence system is... interesting. DA:O was better IMO, but if you look up the guides you can make it work pretty well. Bao-Dur is influenced outside the Ebon Hawk during events, not conversations. It's different than BioWare's conversation driven system, but basically just have him in your party and do lightside things to gain influence with him, and after a couple times you can talk to him about the war and tell him something to the effect that the Force can help him deal with his anger and hate of the Mandalorians. There are a couple of good places on Dxun and Dantooine to influence him, like sparing the wounded Mandalorian on the forest moon.
Mira is best as a ranged character with a repeater or blaster rifle (well, next to HK). She's ok as a Force user but I think that's more of just a perk to her character rather than a necessity.
Recently found this and it sums up this issue perfectly...
