I'm just curious how often shugenja suffer backlash in actual play. Due to the nature of the R&K system, a careful shugenja could choose to avoid it entirely. I could see the Isawa player in my group doing this, as he is loathe to lose control (tempting his Jedi in our Star Wars game is annoyingly difficult). However, I can imagine a few situations in which it would be well worth the cost, even advantageous to just go full Nova.
So, GMs and players, what have y'all seen?
