His passive should get reworked into a Pantheon attack block but his case it would be a CC block. It would have an internal CD unlike Pantheon's or the charge up counter could be ased on damage taken. And he should have a basic ability that have a crit retardant passive (critical attacks deal 10%-20% less damage).

BTW I love his E(even Riot admits that it is a bit OP) plus Ravenous Hydra.
