Some ideas for Volibear. What you think?

I been trying to think of ways to help out the bear. I just want to know what you think.

I think Volibear should uses his frenzy as a niche, Like giving him the power to make his Q and E better when he has all 3 of his frenzy stacks. Like His Q makes him run faster and do more damage than his normal q and his E range is bigger and champs can be feared for 1.5 secs. Of course he can still not use his w without his stacks. So you have to make a choose.

I was thinking for his Alt Sense it shoots out a chain of lighting when activated that is can shoot out more than just one. Like 2-4 but 2 chains lighting is the max a champ can be damaged by. He's also at full frenzy stacks after the activation.

Also for his Q I really like to add on some AP% on it and when he flips a champ when he has thunder claws activated. The damage from the thunder claws hits twice.

I think it's op but I'm trying to think of ways to scale this back something. I was mainly trying to think what would be a good niche for voli and a better ult.

Also tell me your ideas for Voli and or other champs
