His passive is just ridiculously awesome for a tank. At about 3500 health, which is standard for a mid~lategame tank, he will deal (15 + (5 * 18) + (3.5% of 3500)) = 228 extra damage. That's pretty much like getting Blitzcrank's Power fist for free, only without the stun.

Best thing about this extra damage is that it usually confuses the enemy into thinking you're gonna do that same damage for every hit you do. Squishies generally get really scared when an enemy (with no attack items at all!) suddenly take away 10% of their health with a single auto attack.
