Pretty much everyone in the second image, Morningstar as well. I don't see a counter to Crossbones in your roster except for BWCV and I'm not the best with her so I don't know if she could out damage the healing without suicides at R4.What you definitely need to do is start to work on your masteries, unless you're a hardcore arena grinder I'm guessing that you've spent a bit to get through Act 5, it starts to become a bit less effective in Act 6 so I'd take a step back and work on ranking most of that second page of 5* up.I'd go BWCV and Sunspot as your next rank ups. I'd probably choose Blade out of your skill options and then you've got a choice between the Supremes - neither are bad options.
