It's hard to imagine without the surrounding events as context but...I would imagine they'd planned to give her the ship to command for a certain reason? Or with some objective in mind? It'd be disappointing if they'd planned to do it just to showcase her failing as a leader.

I'm not so sure I'd agree that she'd be all that much like Tigh. She had a lot of scorn for his decisions made under pressure situations and...Scar aside, which I choose to see as a bit of a writing mistake...I don't think we see Kara shirking responsibility or letting personal feelings cloud her work/career until...Scar? Kara is also much better at strategy and seeing failings/holes in potential plans (this is a recurring theme for her from Hand of God to Res Ship), so that might have served her well in commanding an entire battlestar.

So I guess it depends on timing, if Kara had become Peggy commander instead of Fisk---so around the time of Black Market--that would have changed a lot. I imagine they might not have pursued going back to Caprica to rescuse the resistance potentially? OR maybe as Commander she would dispatch a mission to do just that? Would've been intriguing....
