I don't like it very much. It slows down the shojin a lot with riftmakers, which are big power spikes because they are percentage-based. As an AD item, you will lose damage on your skills. something that doesn't happen with shojin, as it increases the damage of your passive skills by a percentage, in addition to the CDR being higher. With sundered sky you will heal with the item's passive, but you will heal less with W. in my view, sundered sky is not worth it.

thankss! enjoy this :p
