Keystone Masteries?

The new mastery system is live as of the recent patch. Here I've listed the nine keystone masteries (along with a few notes).

Ferocity:

1. Warrior's Bloodlust: Critical strikes heal for 15% of the damage dealt and grant you 20% attack speed for 4 seconds (2 second cooldown) -Looks like a pretty generic mastery for ADCs and anyone else with heavy crit/auto synergy. Obvious alarming Yasuo synergy.
2. Fervor of Battle: Your basic attacks and spells grant you a stack of fervor for 5 seconds (max 10 stacks). Each stack of fervor adds 1-8 bonus physical damage to your basic attacks against champions, based on your level. -An alternate to #1 favoring sustained DPS (I can see it being good on depending on how it applies, and and )
3. Deathfire Touch: Your damaging abilities cause enemy champions to take 6+50% of your Bonus Attack Damage and 20% of your Ability Power in Magic damage over 3 seconds (Area of effect and damage over time abilities apply half of this damage over 1.5 seconds instead). -Maybe good on AD Casters? Said to work best on poke mages, but only applies at max effect on single-target abilities. ? Arguably Akali too just because she has spammable single-target damage+hybrid scaling.

Cunning:

1. Stormraider's Surge: Dealing 30% of a champion's max Health within 2 seconds grants you 35% movement speed for 3 seconds (10 second cooldown) -Probably good on burst mages. Possibly certain AD champions as well with the path being the only way to get flat ArPen from masteries.
2. Thunderlord's Decree: Your 3rd attack or spell on an enemy champion shocks the area around them, dealing 10 damage per level plus 20% of your Bonus Attack Damage and 10% of your Ability Power as Magic Damage to enemies in the area (30 second cooldown) -I don't really know what this is. I initially thought it would be good on Kayle until I saw the CD. It's basically an extra Lich Bane proc as far as I can tell.
3. Windspeaker's blessing: Your heals and shields are 10% stronger. Additionally, your shields and heals increase your target's resistances by 15% for 3 seconds when used on an ally other than yourself. -Pretty decent support mastery.

Resolve:

1. Grasp of the Undying: Every 4 seconds in combat your next attack against an enemy champion steals life equal to 3% of your max Health (halved for ranged champions). -Lifesteal based on HP. Probably especially good on and .
2. Strength of the Ages: Large monsters and siege minions that you or nearby allies kill grant you 20 and 10 permanent Health respectively (300 max). After reaching the max bonus further siege minion kills restore 100 Health. -Health stacking. Seems sort of slow for what it offers. Maybe good on Sion for his low base HP.
3. Bond of Stone: +4% damage reduction. While near an ally this bonus is doubled and 8% of the damage they would take from champions is dealt to you instead (cannot reduce you below 15% Health). -Pretty solid mastery reminiscent of the Martyr's Gambit thing from Black Market Brawlers. Particularly good for tanky supports.

Anyone see other notable interactions or uses? I just listed a few I saw off the top of my head.
