Of team RWBY? Either Ruby (Barbarian-ish since she moves faster and hits hard but has little armor and strikes slower) or Blake (Assassin-ish because she move fast and hit fast and super strikes). Nepy could be considered, he looks well balanced across the board. Maybe Yang, but in most cases she's a monk-type which means relying on more buffs and debuffs in an RPG with your standard attack not doing much. Weiss... I just suck with magic XD

Of anyone in the series... hmm...

*takes a second to recount the cast*

Raven or Adam (Blademasters ftw) or Jaune, since nothing is wrong with a classic knight in derpy armor XD
