Riot, you're backing yourself into a corner with this new grasp change
I'm a GP main, I only sometimes pick grasp, but I'm more than happy with Klepto so I kind of don't have a horse in this race. That being said, the point I'm trying to make is, does riot really want to group all the tanks and all the bruisers who pick grasp and the ones that used to pick fervor into 1 keystone? Do you think it'd be wise to try and balance all those champions with all the issues and interactions that they may create with this 1 single keystone?
It seems like a fool's errand to me. Why not just take one of the precision keystones and just change it to fit bruisers? That way you don't have that many ropes tied in one knot.
damage puts you in combat and starts and sustains the grasp proc, while allowing you to keep the passive AA.
It is a pain in the ass to get it to work well, but there is a workaround to get it to work somehow, whether it is worth it is another question.
