They both look great, but Deathstroke better be back. I'd hate for an iconic villain to be dropped at the expense of a flavor of the month tie-in character.
I probably shouldn't worry too much, since Superman/Supergirl/Zod, Batman/Batgirl, Joker/Harley, Shazam/Black Adam, and Green Lantern/Sinestro are proof that multiple characters with the same power set/abilities can coexist in Injustice. Two marksmen in a roster of ~30 characters isn't exactly overkill.
