How is Dark Seer this patch?

I haven't seen him at all, but was thinking he would be a nice pick next time I have a pos 4 Spirit Breaker on my team.

From what I looked up, he is hovering at 49-51% win rate depending on rank. I know he's typically best vs agi carrys, he maybe suffers from the tank cores in this meta.

Anyone using him lately and have any input?
