Anivia's Egg
Anivia's Egg has not saved me...never to memory. All it does it slightly delay death.
Under your own tower, no problem, the enemy still kills you.
With a full ally minion wave, no problem, the enemy still kills you.
This ability might make more sense on a tank like Zac. But on the squishiest champion in the game, it does nothing. It's completely worthless.
The egg needs a major buff, both in the revive speed and in the defense you have while in egg form.
