Sion Q tooltip bug [GAMEPLAY]

Right now, there is a bug regarding Sion's Q. The damage it deals to minions matches the functionality listed on the website here at 60% damage to minions, but the tooltip still states that it deals 80% damage to minions.

The last documented change to his Q as seen here in the patch 5.6 notes indicates that it was supposed to only be nerfed to 80% damage to minions, which is consistent with the in-game tooltip.

At this point, it's unclear whether this was simply an undocumented nerf that slipped through the cracks or if this is actually an unintended change, but either way, fixing i would be greatly appreciated.

If/when you do fix this Riot, can you give Sion the benefit of the doubt and buff the damage back to the tooltip indicated 80% so that he can jungle again? I've missed using him since he got gutted, and his win rate and picket aren't at a level where a minor buff like this would shoot him to the top of competitive again.

Also, this tooltip/Q error is 100% reproducible in my experience, simply by using the ability normally on a wave of minions or a monster camp.
