A) He's very strong. One of those champs that can kill anyone lategame, and is pretty strong in lane as well. Also, one of the few "counters" to yorick.

B) Yes, he can. I'm not a fan of it, but I've had great success in normals with jungling him.

C) I'm not entirely sure, but at that point it's probably Guardian Angel and either a tank item or a damage item.
