I use RF as my main front liner if I'm fighting the big teams as a damage soaker so he can fully utilize his SA. Stacking 50% DEF on top of health makes him extremely hard to kill especially if he gets around 3 to 4 stacks of armor. Count on top that, he can stun people if they are ones that do alot of combo hits such as Painwheel or Fila then he can still dish out decent damage. (Not on par with something like Private Dick or Epic Sax, but still decent.)
