I hear a lot of folks mentioning Paladin (well, not in this thread, but :P).
\Was just on my way down here to write "paladins."
Also, Hexblade warlocks. And any type of bard.
But maybe most of all? Barbarians. Because I think it would make a lot of sense for them to shove people extra hard while raging, and I want to see the little gobbos fly.
