Is Volibear Cancer?

Edit: I meant a 3v3 between my friends, in a custom game, in summoner's rift. Not like 3v3 Twisted Treeline

Question explains it all. I've used him recently, and whenever I get into 3v3 (Summoner's Rift) they always complain about how OP he is. I'm not new (level 30 but no comps) but I don't exactly have the knowledge of the universe of league.

Now, let me stop you there if you think these people are the casual whiners. IMO I think they are better than me and have been since I started this game (one of them starting at the same time and still accomplishing more than me). (Haven't played ranked) I have won at least 90% of my games as Volibear and his abilities seem overpowered, with a disable and the ability to jungle without a leash, along with cc and a high damage bite without any damage items needed. And don't get me started on the passive.

Even if he is cancer or not, I just want to know one thing mainly: Is there ways to counter him? Why? Well, I'm not a selfish jerk and I want to show my friends that it isn't completely fair and there is always a way around things, help them out to counter a champion AND when I queue how to counter the counters. Thanks, a hopefully not bad player
