His passive essentially blocks 40% of minions autoattacks at all levels, since creeps can't outdamage it. If they changed it to 100% chance of blocking 12/16/20 damage, he would become immune to melee minions while blocking 50% of the damage of ranged creeps. That's why his passive is random.

Also, the new passive you sugested is probably stronger than you think.
