Rito, what are your thoughts on the Resolve Keystones right now?

Bond of Stone is garbage and basically never taken, Grasp of the Undying is outclassed by Courage of the Collosus, and Courage seems nerf worthy at the moment. Are there any plans to nerf Courage and potentially alter the other two? I like Courage personally because it doesn't contribute to damage creep. Also, Bond of Stone seems kind of uninteractive and outclassed by Knight's Vow. Has there been any dicussion about replacing it with a more generally appealing option?

Outside of the keystones, there are several issues with the lower tier masteries. If lower tier masteries are supposed to be about early game, why is Unyielding in tier 1? Wouldn't it make more sense to switch its placement with Veteran's Scars? My understanding is that Perseverance is outclassed by Insight and Fearless on the vast majority of champions. There was a similar mastery called Second Wind that increased healing when at low health, which seems to be a similar effect. The old Perseverance gave health regen equal to 1% missing health, which also seems to be better. Legendary Guardian is also almost always outclassed by Swiftness (at least to my understanding). Adaptive Armor was a much more useful mastery even when both existed in season 5; maybe it could replace Legendary Guardian?

I'm personally saddened by the fact that most of the masteries seem to have clearly better options. I think Fearless was a great addition because it can actually compete with Insight on champions that aren't very reliant on Flash (or Ghost for that matter). I would like to see more changes to the Resolve tree to make it more consistent with the view that the lower the tier, the more early game and less impactful the mastery is, AND create interesting tradeoffs in masteries where one doesn't outclass the other on 90% of champions.
