There really needs to be a defensive keystone for tanks/bruisers vs range.

Of all the keystones it seems like there's something missing for tanks. Almost every keystone is geared toward damage to make use of them.

In the resolve tree which is the tank tree for keystones you have:

Grasp of the undying, Geared toward doing damage w/self healing and health stacking which is ok if you are able to trade damage with your enemy, but if you aren't then it's nearly useless in lane

Aftershock - Another damage focused keystone, good if you have a stun/taunt, but if you don't it's another useless keystone for many top tanks/bruisers.

Guardian - Useless in lane if you are not support.

So of all the keystones in this tree there's not a single defense focused keystone for melee tanky characters.

Playing top as a melee tank there is literally not a single keystone that's helpful for you if you are vs a ranged harasser, nothing. Not only are you going to likely be down farm, but they are going to have a keystone that will help them do even more dmg while you, as a tank, have access to not a single keystone that will help you vs them.

I mean take Garen/Nasus, etc top. Now Put them against a Kennen, Vayne, Teemo, Quinn, etc. What keystone do you run to help you with them during the lane phase? It seems like there's an obvious gap here for that kind of tanky/bruiser role top vs ranged characters.
