Balance Opinion: Guinsoo's Rageblade

The proposed changes are giving the 15% resist pen upfront, making the phantom/double onhit be every 3rd auto instead of every 2nd.

I'm a fan of this intended change. It won't solve all of Yi's balance issues particularly his immunity to AS slow, his true dmg onhit skill, his untargetability (i think it's actually supposed to be immunity since I've seen vanish's interaction with ignite) dash spell and the cooldown nuances around that from ult and autos on-hit, but this post isn't about Yi. The change should fix vayne's super spike issues to but this post isn't about Vayne either. This post is about the fact that Rageblade was probably OP and may now be balanced.
