Replaced it with a shield when you CC enemies.
I don't know how I feel about this.
It could much more significant for the common users, but we'll have to see.
Edit: Can anyone with a PBE account check out the values?

Big Lincoln1 votes2 of those champions have hard CC?
Ralanr1 votesPlus this feels like a Shen buff since now his E can reduce damage again.
Mira Arya Enthe1 votesWOOOOW! This really messes Shyvana up
WoonStruck3 votesJungle Leona might be more usable though. Lol.
GULAG 4 U1 votesFervor on shyv is pretty good?
TyrekGoldenspear3 votesNot to worry, they're adding more items + a smite heal on all her camps. You'll still get a pretty healthy clear.
And if it's overall tankiness you're worried about, armor pen got nerfed a little, so your Shyv's natural armor just got harder to crack.
WoonStruck2 votesIts more that the health was invaluable because it canceled out a good portion of the other damage keystones or other champions' burst. This was extremely useful because it was nearly suicide going more than one MR item unless you can afford to go full-tank. Not to mention the extra damage on Titanic/HP scaling champs, if you're into that.
TyrekGoldenspear2 votesAh, that makes sense.
Well we do have a missing spot in the resolve tree...
Mira Arya Enthe1 votesThe health is for if you buy a Titanic Hydra and/or Cinderhulk and/or to make her less squish early game if she goes damage route.
TyrekGoldenspear1 votesAh.
Well good thing Shyv changes are upcoming.
She'll get some love yet!

WOOOOW! This really messes Shyvana up
Don't you run Fervor on her anyway?
Mira Arya Enthe1 votesYes and no. Fervor is risky, but pays off mid and late game. Depends on the matchup. But the #1 Shyvana guide of all time, suggests strength of ages for earlier dragons.
Primaquarius1 votesI mostly play tanky Junglers anyway, if I ever play Jungle, so this is a nice addition like a reward for securing kills for your team when ganking or teamfighting.
WoonStruck3 votes~~Yeah, except its probably going to be something low like 50 or 100 so champions like Alistar aren't broken with it. ~~
Essentially, in the majority of cases, you will get less out of the keystone.
Primaquarius1 votesIt would scale with health, so 100 HP on a tank jungler would mean its useless on damage junglers
WoonStruck2 votesIt should scale with health. This is Riot we're talking about, though.
Always conservative with tank buffs, always liberal with anything else buffs.
Malicious Metal2 votesIt'll probably scale with max HP else I'd be useless or overbearing on damage dealers
WoonStruck2 votesIt'd move people away from TLD, Fervor, etc.
I'd be willing to take that potential trade-off, considering most damage dealers can't output a lot of CC.
I'm also willing to bet soft-cc won't activate it, unfortunately.
Ralanr1 votesActually I'd be happy if soft CC didn't activate it. Would help differentiate tanks and juggernauts.
Big Lincoln1 votes
would still benefit from this, technically
since i play voli in the jungle this would probably be superior to grasp now, who knows
WoonStruck1 votesIf its champions only, probably not, especially if it doesn't consider additional shield for more targets hit provided slows apply it at all.
SwiftKitten881 votesso this screws over every champ who got the mastery because they NEED hp and DIDN'T have very much, and who DON'T have CC like 
Mommy Elise1 votesI'll miss it on my spider, but Thunderlord's isn't a total downgrade, honestly.
