Interesting points, you're the first one not to complain about his bad DPS from his Q or his stupid bonus AD ratios xD

But to address some of your points, E's range isn't really all that big, it's essentialy Urgot's Acid Huter's range, and although it is somewhat perma-slow, it's only for 4 basic attacks hence his no AS steroids or good base AS statistics. And although, it's a big slow, you're mostly going to be focusing a single target, most likely the tank, since you can't step closer in the fight due to your marshmellowy-squishy-self. The only time when the E's really strong is in the lane phase, but then again, that is Seannamus' strength - the lane phase.

The passive, in my opinion, works well with his ability-spaming kit because of its potential to poke; when the passive is available, it turns into a 1025 range auto-attack, and plus its AoE. And again, it is kind-of strong in the lane-phase, turning into a 130% AD damage basic attack. Additionally, it's free wave-clear.

The ultimate is complicated... (spell-spamming death machine XD) I don't think you've read the ability information carefully - the damage increase through spell-casts accounts only accounts the spells that hit at least one enemy. Since he's all skills shots, I don't think it'll reach higher than 6-7 landed spells (the passive doesn't count as a spell). It isn't really a problem, unless you use scripts :3
