[Priest] Shield battleground vehicles

You can currently shield vehicles in battlegrounds such as Strand of the ancients (Battleground demolishers ) and Isle of Conquest (Glaive Throwers) with Clarity of Will - Spell - World of Warcraft. The shield can absorb half of the targets health. I'm sure you can find other stuff that is not supposed to get healed or shielded, which you can also shield with Clarity of Will.
