Thanks, I'm glad you enjoyed it.

Anyways, unusual picks may be strong nevertheless, and they have the advantage of being... unusual. Many people cannot play against a Poppy jungle. Chances are they do not even know what to do when she appears on your lane. They likely do not even know that she can dive easily with her ult. The same with jungle Blitz, Leona or Twitch. They are all viable.

And still, we have underused jungles. Those are the champions intended to be junglers, but having much less popularity. Like Trundle or Shyvana. But anyways, they are still played from time to time, and that is okay. We cannot expect every champion to have the same pick rate, can we? :)
