It really is the passive. With a lot of health and a lot of mana you can tank a lot of damage in a clutch. Support Blitz won't usually get a large enough shield but any other Blitz or a fed Blitz support can buy Tear, Rod, Iceborn, and Frozen Heart which creates an impossibly large shield to overcome when fighting him.

Most of the time though he just makes an okay fighter, and being used as a support he doesn't get to be good at either roles.
