STANCE ACTIVATION: Udyr's next attack stuns his target for 1 second.
PERSISTENT EFFECT: Udyr's is granted bonus movement speed. This bonus increases by up to 200% based on [how far he's travelled / how long it's been] since his last attack and his attacks slow for any additional amount of movement speed generated this way. The slow decays over 3 seconds.

• MOVEMENT SPEED: 10 / 12.5 / 15 / 17.5 / 20 %
• SLOW/EXTRA MOVEMENT SPEED: 0 to 20 / 25 / 30 / 35 / 40 % after [5000 units / 10 seconds]
• TOTAL MOVEMENT SPEED: 30 / 37.5 / 45 / 52.5 / 60 %

still really wouldn't save him from getting kited ATM, his ability to spread stuns is far more important in team fighting as he can be an annoying combo disruptor.

Udyr honestly is fine...

While he has issues with closing against players in ganks, there are a lot of things junglers can do to win games beyond ganking.

Udyr's ability to knock down turrets, counter jungle, and kill objective mobs is really really strong.

And in a team fight, he can still be a really tanky beast who can maul a carry.

Not to mention he is a strong duelist making him an excellent counter ganker...

I'm not going to go out and say that Udyr is the best jungler out there...but he certainly is viable and competitive.

I've been keeping an eye on one of Saintvicious' smurfs and his second most played champion is Udyr. I wouldn't be surprised with how broken BotRK is right now if Curse pulled Udyr out this week.

While I like the increased movement speed idea your suggestion that only his stance activation procs only 1 stun would kill him in team fights.
