New grasp seems pretty underwhelming.

After a few games on PBE I've found that the new grasp is essentially the same as the old one with less impressive particles and sound, with this false premise of high tankiness in that it gives 5 hp per hit.

In the games I've played, at least toplane, I've never managed to get more than 150hp from this, and have never dealt more than 500 total damage.

While this mastery does scale well with both demolish and overgrowth, it still seems incredibly underwhelming at least in omparison to other keystone runes. The attackspeed rune especially seems to be incredibly powerful, allowing you to permanently transcend the attack speed cap and then some while not sacrificing any onhit damage, crit, or ad to do so.

It becomes even more underwhelming in teamfights where its impact isn't even noticeable, if it gets used at all.

It may just be that the attackspeed tune is incredibly overpowered, that being the only other keystone I've tried, but in comparison grasp is an underwhelming and slight power up from its current iteration.
