Volibear's ult might need a rework

Let's start off with the obvious; Volibear's ultimate has to be one of the least exciting ultimates ever, all it does is give you, a tank, stronger auto attacks... What's worse about it is the fact that its actually really oppressive and a bit awkward at the same time.

When Volibear hits level 6 he spikes HARD, being able to shred multiple health bars at the same time and essentially 1v2 an unsuspecting laner and jungler, and this isnt even talking about if his laner helps him out, and even then its cooldown is so low that he can just use it on dragon and take it as if he's Udyr with a flip.

But then there's the fact that its pretty uncharacteristic, for a Freljord champion he doesnt have much CC, being the only one besides Nunu and Olaf to not have a stun and lets face it Nunu doesn't need a stun and Olaf does way too much damage to get one. Volibear also needs a more reliable engaging tool because right now all he does is run at you and that has to be one of the most predictable things I have ever seen in the game, like, as predictable as a long range Nami ult, making him farely unreliable to an extent just because when he tries to engage its as simple as hitting one stun on him to stop it.

Don't get me started on the elephant in the room, he is a tank with a pure damage ultimate, meaning late game if he didnt have his W it would be utterly useless, and its still pretty meh without it, out of all tank junglers he has the most pitiful late game I have ever seen due to him not having the ABSOLUTELY CRAZY AoE CC that is characteristic of tanky champions.

Do what you will if you try to change it up, just make it a bit more fun to use. Bring back the bear.
