Just making sure, you know this guy has Pursuit as well, right? It's a class skill for Snipers.
2.5/10, the only Wyvern guys your actual 1-range crew has trouble killing have Nihil, so I really don't see the point in this guy (or Faval for that matter). He is alright at fighting but can't do anything in any kind of realistic efficient playthrough, unless that pt somehow forces you to incorporate all substitutes or something.
