PSA to Junglers
If I'm leashing a buff for you, I'm expecting you not to smite it so I'm going to keep doing damage to it until it is fairly low to speed up your clear. If you do smite it, PLEASE make sure it's HP is below the smite damage, otherwise there's a possibility that I will steal the buff. Had this happen recently in a plat game, and the jungler blamed me for it, even though I couldn't cancel my auto in time after he smited.
