@Riot what role is Shaco supposed to fill?

I honestly can't tell what he's supposed to be. Is he a bruiser? A fighter? A tank? If he's supposed to be an assassin, how? An assassin is supposed to be capable of killing an enemy carry very quickly. Shaco can't do that after the nerfs- building him full ap or full lethality still won't kill anyone before his long cooldowns leave him stranded. Meddler said that his nerf is okay because he has "tricks" but that seems to mean he's not expected to do anything without his ult, which is pretty counter-intuitive for the champ we all know "dominates early, falls off late".

I can't tell what direction Riot's intending for him anymore. Triforce into full tank was the dominant build before the nerf and it'll continue to dominate anyway, but I miss being able to actually kill people.
