A good conservative page would be AD/AS marks, armor seals, MR/level glyphs, and then opposite quints to whatever you took for marks. So if you have AD marks you want AS quints, and vice versa. He's an AA reliant champion, so more autos benefits him a bit more than just straight AD or armor penetration. This also means that he's going to be doling out his on hit effects more often, including his own passive healing benefits and the eventual lifesteal you should be building. The little dose of AD is mainly to help your initial clears.
