the resolve tree is complete and utter trash.
there is no incentive to go into that tree anymore. except maybe for junglers simply due to the lack of options when it comes to a different keystone. not even because its anywhere near good, but only because no other keystone helps them jungling.
after the nerf to grasp, its in my opinion not even worth for fighters anymore. the only point of going into that tree was for the damage/sustain of grasp. now you would be only going into that tree for a damage keystone since the health return is neglectable.
but why do that, when ferocity and cunning have so many damage amplification masteries down to their keystone, that just going into resolve for grasp would be pointless?
every auto attack focused fighter should go into ferocity for fervor. everyone else should go into cunning for stormraider or thunderlords. else youre doing something wrong.
for season 7, can we get a defensive mastery tree with actual defensive masteries instead of a utility tree with some laughable base health regeneration bonuses and 2 flat damage reduction against auto attacks?
maybe an actual defensive keystone for solo laners aswell, if youre going to keep the concept?
and more still go way into the defensive tree...

all go down the resolve tree.
