That kind of rapid-fire teleporting quickly exhausts Nightcrawler. His range being limited by what he can see, he could only use this tactic if he had a view of the open sky. In addition, at the moment he reaches the apex of his ascent, he's already starting to drop, so it would be too late for him to avoid being affected by the inertia of a fall.
He could make it hard for Wolverine to catch him, but he has no feasable means to hurt Logan. If he tried to punch or kick him, he'd just break his hands and feet.
Or if he tries rapid-fire teleporting with Wolverine in tow (and this is making the assumption he manages to grab Wolverine without getting clawed up), that won't work either. Wolverine is more resistant to the fatigue and pain of teleportation, he'd still be able to turn around and slice Kurt open whenever they landed.
