OMG. They are actualy nerfing lee sin!
Smite isn't a spell anymore. No more free health from his smite+W.
I hope 6.2 doesn't come with: "Since lee can ward hop to wards and braum can't , it makes doesn't sense that hecarin can't proc health from the new changes. So lee sin get a free out of jail card and can now proc spell vamp smite."
