Grasp of the Shielded? A proposal for a better keystone
I was reading the Grasp of the undying changes today and I had a thought. What if instead of replenishing health you get a shield every 10-20 seconds or something while in combat based on 3% of your max health (similar to Vi passive where she gets a shield when using an ability) which would accomplish damage mitigation without providing tanks with infinite sustain that they shouldn't have in their kit. It would also introduce a means of counter play, the shield lasts a second or two so it could be played around and provide offensive bonus to aggressive top champs without providing them sustain to players who can outplay the shield duration.
This would establish Grasp as a more aggressive choice for smart play and Strength of the ages for a measure of defensive stats and sustain once the health proc is maxed in lane without being too oppressive.
Thoughts anyone? :)
