The decision behind his shield was compound:
 * Retain his current mana-orientated build, rather than people trying to build him like Jinx or Kog'Maw. He is still mana dependant, so it's a form of positive encouragement for the correct build.
 * He's immobile and slow, but I want to discourage him building tanky like Graves did. Having a rapidly generating shield and low health pool makes his overall durability poor, but he still has burst proofing.

And yes, Artillery Strike is a vector skill shot.

And thank you for the praise!
