Strength of the Ages- Changing It to a More Pure Tank Keystone

Strength of the Ages

• Health gained changed from +20 Health from Siege Minions and +10 Health from Large Monsters, up to 300 bonus health, to +1% Bonus Max Health from Siege Minions and +0.5% Bonus Max Health from Large Monsters, up to 15% Bonus Max Health

Right now, Strength of the Ages has a bit of a weak identity in my eyes for working towards a specific champion type. Right now, it's just kind of picked up by every single champion that goes Resolve that isn't a Support or uses basic attacks. Every single champion that doesn't make use of another Keystone just goes Strength of the Ages basically. However, I want to change it to where now Strength of the Ages is more focused on Pure Tanks by giving them % increased max health instead of flat. Now, the keystone has an identity of the Pure Tank keystone, which wasn't actually a type of keystone before. Not saying Strength is WEAK at the moment, it just isn't like the other Keystones where it's an exciting pick up for any champion that uses it.
