It amazes me how riot is still not nerfing grasp of the undying.

This keystone is so freaking op. The "cooldown" on it is WAY too low for what it does. You might think that 3% max hp is not alot, but think of it this way. I've been using this keystone on so many champions as of late and it honestly has broken the laning on some.

A tank with 3k hp, will steal about 90 life every 4 seconds. A mage with thunderlords will deal 180+ 10% ap bonus damage on a combo of spells. 15 second cooldown. So over this 15 second period of time, a 3k hp tank would have stolen about 360 hp. Even with lets say 500 ap, this tank would have out damaged the thunderlords proc very easily.

The 4 second "cooldown" is way too low. Even in low levels and with relatively low base hp, this mastery breaks some champions. Not only are tanks really hard to deal with currently thanks to the genius Last Whisper nerf, now full tanks with 0 damage items get to deal insane damage thanks to this mastery.

Nerf this mastery already.
