Make Sion Great Again !!

I had an idea for a Sion buff which sounded awesome in my mind at least. Like every Sion player knows about this attack on towers where he slams his shoulder into the tower whilst putting his weight behind the attack. But its the only time he uses that attack animation. And it looks pretty brutal considering he has this shoulder gaurd with these massive spikes on them^^

What if Sion would have a different use for that ''attack'' aswell. What if he uses that attack once every 6 attacks reduced by 1 for each rank in ultimate. So once every 6 attacks pre level 6 and at level 16 once every 3 attacks. The attack would deal bonus physical damage equal to 3% of Sions maximum health and apply a bleed effect for 2 seconds dealing 50% of his bonus armor and magic resist as physical damage over 2 seconds ticking every half second. This attack also applies the grounded debuff for 2 seconds Can't happen more then once on the same target every 3 seconds.

Just something to give Sions attacks a bit more heft and make him more dangerous to stay near.
