Expert take
Rengar is an excellent pick for players who like to dictate tempo through information, not just damage. He rewards patience, stack preparation, brush control, and reading enemy movement. He can feel unfair when he appears from fog and deletes a target, but that outcome rarely comes from a single button: it comes from hidden pathing, a prepared angle, and a timing where the enemy no longer has the right to walk alone. If you want a jungler who creates fear across the map and turns every vision mistake into immediate punishment, Rengar has real value. If you want to engage frontally without setup, he quickly becomes much less reliable.
