Turtle Stance shield was stronger and the mana/health gain on hit was much higher than current numbers, I think it was something like 12/14/16/18/20%. Made him tough to take down in the lane and in the jungle, zero mana problems and soloed dragon at 3. Phoenix Stance's numbers were bigger as well.

The thing that really broke Udyr was that his Monkey's Agility gave multiplicative speed instead of additive. It also gave 15% attack speed per stack instead of 10%. What this meant was...

Lv1 old Udyr at 3 stacks: .967 attack speed
Lv1 current Udyr at 3 stacks: .867 attack speed
Lv18 old Udyr at 3 stacks: 1.625 attack speed
Lv18 current Udyr at 3 stacks: 1.321 attack speed
Lv18 old Udyr with 3 stacks and any 40% attack speed item: 2.012
Lv18 current Udyr with 3 stacks and any 40% attack speed item: 1.587

Udyr was able to maximize his attack speed with very few items (most would get Malady because it would put him at around 2.2 by itself) and then focus the rest of his gold on hitting hard. I saw a few who played with a full aspd runepage, hitting at almost 1.4 attack speed right out of the gate at Lv1.

Attack speed is normally not that great of a stat, but simply having that much of it that early on in the game, and the innate life/mana steal of Turtle Stance allowed him to snowball completely out of control before anyone else has a chance to stop him.

You probably won't find any videos because it was only about 18 hours before Riot saw the massive QQ on the forums and fixed it.

you solo'd mid, stayed in turtle form and farmed while ignoring your lane opponent. if they overextended, you harassed/killed them.

I wasn't around, but I heard he pulled pentakills harder than Pre-nerfed Xin and Brolaf combined.

Oh wait...

Items: Mercury Threads, Randouins Omen, Sunfire Cape, Negatron Cape (if I had a bit more time, I wouldve evolved it to a FoN or Banshee Veil, but the other team surrendered early, lol)
