The passive looks fine to me. It works like Hecarim's Q, not like Ryze's passive. He'll need to build it up and keep it going to benefit from it.

His numbers may not seem high, but let's take a look: I don't really know how his W interacts with his Q, but if it bounces off each enemy hit, everyone is hit twice. That gives a 380 (+100% AP) AoE ability on a (best case scenario) 1.8 second cooldown (if CDR is disregarded entirely when his passive stacks, it would be 3 seconds).

His E is strong on itself (best case scenario: 240 (+50% AP) damage to all enemies within reach every 3.6 (6) seconds) and also doubled by his E (since it hits all enemies and bounces off in an area, giving them 480 (+100% AP) damage). I assume his W makes his E bounce off the first enemy hit only, or this would just melt entire teams.

On top of that, he gets a Thornmail passive.

I'd defnitely try to build this guy as an AP-tank: (1) surviving to get the passive stacked and to get the most out of that sweet 30% movespeed; (2) have the Q hit as many people as possible as often as possible; (3) sweet Thornmail passive is perfect for it; (4) he lacks any form of CC or escapes, so it'll be his only survivability. I also love how his E deals the most damage to the enemy's team by casting it on the enemy tank :)

"His ultimate is supposed to be a range-independent finisher." If I was playing this guy, I'd save it for teamfights to cast it on the enemy tank (for the W passive) as soon as he stands close to his marksman/teammates, nuking them all.

tl;dr Very interesting and nice design and, I believe, very powerful, too. He may not have a lot of mechanical diversity (just press Q and E), but even more so on a tactical scale.
