New passive is good (and at least you don't loose 2-3 spell cast when struck by a nuke late game).

And for Empowered E, if someone say that the healing has been nerfed, let's compare :
 * Old : 6 bounces that refund (of the mana) heal, so a max of  of the amount of mana per hit.
 * New : bounces that refund  (of the mana) heal, so a max of  of the amount of mana per hit.

It's a buff of of the amount of mana per hit.
