I never said she used her power in the pilot, only that the implication was that her power was something that made robbery very easy for her, explaining why she wanted to feel the rush again.
I really doubt that her empathic dreaming, as presented, would help very much in such a career either. It's all symbolic. In the scenes we've seen with her, none of them have appeared to be literal. So it wouldn't do a very good job of casing a joint, finding out where security will be, learning the combination to a safe, or any of the other solid information she'd need. At least not without spending an exuberant amount of time doing it, researching, and puzzling things out.
I mean, sure, it's easy to say "we never learned what her power was, so it could have been anything." That's exactly the point. But it doesn't fit smoothly with what little we do know from the show. You have to do some serious rationalizing and hammering square pegs into round holes to make it work. Which is why I was pretty disappointed in it and pretty much most of what they've set up with the stories for this season.
