Does Merc Scim even serve a purpose anymore beyond Malz ult?
There are far better offensive lifesteal items, and Hexdrinker is better for defense against AP. The active is borderline useless now with every team, and nearly every new champion, having layered CC and knockups. It's just an "Are you playing against Malz?" item.

against an Ashe?
