Champs that dissappear

Vanishing is very powerful. It is usually done in tandem with or right before an offensive ability, and makes you un-targetable.

So its offensive and defensive. It adds confusing to the battle which requires time for the opponent to get orientated.

Now let me ask you this. Do these champs like Yi, LeBlanc, Fizz etc do anything less well? Do they scale less, do their abilities do less?

No. Basically champs that vanish are inherently more powerful then champs that don't vanish.

Fizz is the most bullshit of all. He gets all that mobility, while being untargetable, and does super amounts of damage? Come on now, this isn't a display of and kind of balance. This is just a bullshit champion that is too good at too many things.
