IIRC Captain Britain will be the next platinum pass chase champion and from what I've seen she has disappointing numbers even after the buff. Nick136's test showcases her underwhelming finish time. I personally don't think a lot of people are going to be buying the platinum pass unless they want the units(the only good value). I always buy every platinum pass but for this one I'm definitely passing.
