I didn't play as a Siren in the first, but I'm considering a run as a Siren in the second. Can somebody fill me in on how the two abilities differ? Or is it a very small difference, like the two turrets?
^ This Phase walk made Lillith literally a "Walking machine of death" literally setting every thing on fire etc as she passed by. I didn't play her but it was fun watching my friends use her and see the path of destruction she left behind her.
