Volibear's Passive is pretty annoying when you dont have your ignite

Nidalee has one of the best passives in game.

Ryze's passive is almost broken and OP on him. Put it on somebody like veigar; and it's kinda stupid though.

Really the best universal passive IMO is fizz's.
A flat amount less damage from minions, AND no-collide with units. That would be SOOOOO nice on SO many champs.

Rengar, jump out of bushes, get a kill. Proceed to win the game.

If Janna's passive is so great, why isn't TF's better?

I think Karthus, Kog'Maw, and Zyra's passive are all pretty good.

But I'd say the best has to be Volibear. In my opinion. He's so hard to kill.

Poppy by far.

The shenanigans you can pull off with that passive. Usually induces rage or overpowered crying in all chat.

Volibear's passive is up there, but I'd have to say Karthus' is the best, 8 seconds of life can get at least a kill in a teamfight.

Ill have to go with Lux because even if your dead and they had the littlest amout of health you spell withh do a great amount of damage
