I like the idea of taking out the heal from grasp that seems fair but please don't take away the permanent health that is honestly the only reason that it is even viable in the first place IMO. Especially for players who like to play sion, vlad, mundo, etc... These champs may be strong but only fill very niche rolls and I feel like taking away the small amount of health you may gain from grasp feel as though they are even struggling harder to find a place in the current meta.
Yeah I mean if you take away Sion's second infinite scaling HP, he will only have 1 infinite scaling HP ability left.
I'm pretty sure that the heal isn't getting taken out but actually increased to 4%. The damage is what is being taken away. Either way, I personally hate this new grasp since not as many champions will really use it. It seems broken on champions like yorick, trundle, and shen. It might be op on nasus too but I'm not sure since he is currently doing really well with kleptomancy. People who could use grasp like poppy will most likely not use it after the update. This rework will force her to either build to split push or force her to teamfight with aftershock.
Really if the stacking health wasnt so bad along with the whole grasp tree being bad id use grasp for 
and other champions with stupidly low hp pools but still build some defense.
