Udyr is a Juggernaut - That begs the question: Why is he so goddamn so squishy?

Whether you max W or not, is irrelevant. The guy is squishy as hell.

While Udyr is not a team fight champion, but goddamn that most other Juggernauts have the capability to sustain in teamfights. Garen with passive and W, Darius with his Q, illaoi with an R, Mundo with R, Trundle with a W, R and a passive and Volibear with his Passive. And unlike the other champions, they scale well with health items and a single damage item, because they do % health damage in someway.

Udyr on the other hand, if he doesn't build damage, he is a wet noodle. If he doesn't build tank, he gets destroyed but he is the most useless champion during it. Nevermind that his damage falls off, really hard compared to other fellows here.

Meanwhile Udyr does have a spammable shield, it does jack shit during teamfights when it is on a high cooldown relevant to teamfights burst orientation and it doesn't do any form of damage, and by the time teamfight begins, Udyr has no resistances - his core has been Warrior and Triforce for now - if games get stalled, he is soon begin to lose.

I prefer the old style with Phoenix, where your Jungle item did on-hit damage, healed you and you had lifesteal on W, rather than this useless % healing.

Solutions? Revert his W to lifesteal, and buff his R for time fights, or bring back Sterak's damage as Bonus Base AD at the least. End all.
