Or you could just make a separate roster for them as the original poster suggested. I don't have any room for R&D Doffs on 3 of the 4 characters I have checked so far and unless there is a separate roster, I don't see me starting any R&D projects any time soon.
I would like to see a blue winter jacket. I'm easily pleased, oh and the epohh reseacher's voice box removed and the races nerfed so I can actually win one.
