Pursuit would just do the damage Crunch does in a situational circumstance, while doing half of the damage most of the time? Just beginning to try competitive and I don't understand this. Even if it does do more % wise when taking in consideration 40 + STAB x 2 is better than 80 + STAB (if that's how it works), how is that risking the chance of them not switching out?
I just got a 4IV Jolly Larvitar with Stealth Rock, Pursuit, and Dragon Dance egg moves and I don't understand why someone would go out of their way to put Pursuit on it. Sorry if this is a really dumb question.
