RoA plus great scaling % magic damage on W is the reason he sees play top lane. His ult is also better now if he dives into the enemy team and can be used as additional burst.

He just buys RoA instead of Golem and goes to town with the tank items. Also, TP gank meta at which he is pretty much top tier.

Those are the reasons. He was sort of okay before, but his W is now an A++ spell that does so much damage with very little AP (again, just RoA).
