Here is a giant exploding crystal. What does my Melee DPS do after he is done with his current enemy? Boops the crystal and kills himself in the process...

It would be nice if the duel system had some form of limiter so that when you are just beginning, you don't have to go up against over level 100 characters in which you have no chance of winning against and essentially just dropping 4000 gold down the toilet.
