Pretty much this if you're set on only having one page, though I would suggest at least two.
Almost every champ will at least occasionally harass or last hit minions with their auto attack, so even champs that attack damage isn't useful for will still slightly benefit.
Except for Singed. I am still not positive that he has an auto attack... I mean I'm pretty sure he does, its just that I've never really seen it.
