6 second revive might as well be 6 years in a video game like this. That revive should be at most 4 seconds, preferably 3. Even a mage completely out of mana getting attacked by the tower can easily kill the egg before you revive. All it does is delay death by a short amount. It makes no sense.
Aatrox is fucking 3 seconds.
Zac is a TANK, starts off with 8 seconds but slowly changes to 4.
Anivia is a squishy. She can't tank for 6 fucking seconds.
