That's because most of you are low rated and don't play with decent players.
The issue is that Udyr is 100% worthless in team fights against spammable slows. Very few other champions are shut down so hard by a single champion.
Take a game against Jax, Kassadin, Ashe, Janna, and Galio.
Udyr cannot touch Ashe, she kites him to death.
Udyr cannot touch Jax, he's permanently slowed and Jax just leaps away.
Udyr cannot touch Janna, Ashe doesn't even need to slow him; she can alternate her slow and then cyclone him when he gets close.
Udyr cannot touch Kassadin, he's permanently slowed and Kassadin just Riftwalks away.
The only person Udyr can hit is the enemy team's tank, which accomplishes absolutely nothing.
**** like this shouldn't be acceptable.
