Trundle's Pillar activates Courage of the Colossus

Because of the small knockback when you hit an enemy directly, it counts as hard CC and gives him the shield, and it can get pretty scary. I only played against it once, against a support Trundle, so I can't tell if it's balanced or not (and we won that game btw) but I think he's pretty strong already and doesn't need an extra shield. Is this intended or an oversight? Also, I bet it works with Anivia too (though she doesn't go resolve)

P.S: sorry if this is the wrong board, but I thought that technically it's not a bug
