So I don't know if this will be enough to matter, but

Level 13 (both maxed) EQ Just went from around 1045 damage to around 1206 damage.
Each additional (non-sheen non-q) auto gets another ~20 damage.
Seems like maybe this will be a soilid core build on him now that duskblade's been nerfed? Or at least worth considering if you're already playing him, it might not be good enough to justify playing him in the first place.
Added bonus of giving all the fun passives and stats of the two items, and of course his new Q keeps mattering more the more bonus ad you build.
