Why Is Teleport/Smite Underplayed?

Statistically, teleport/smite is played just over 0.2% of games. Albeit, I didn't expect teleport to be picked more often than flash, I still expected that teleport would be picked a lot more than only 1/500 games. These statistics are from Udyr, who I think would benefit more from teleport than other junglers, due to Phoenix Stance and the current Runic Echoes.

Teleport allows you to gank, counter, pressure, and increase your overall presence. Not to mention split pushing, and the fact that most players can improve decision making to reduce flash usage even further. While I'm not trying to argue that it's a better spell than flash, I think it deserves a lot more than 0.2% of games for its usefulness.

From personal experience, I've had almost a 90% win rate with teleport smurfing bronze, losing only due to AFK's. Of course, this data cannot be generalized to all divisions, for reasons such as lack of map awareness, prominent in bronze.
