So exactly wtf happened last update?. I logged in on my Spellbreaker today
after having actually spent more points into physiqe and find myself having
lost almost 3k health, from 10k down to just over 7k health.
I haven’t changed any gear or devotions, and last time i played, my character
was sitting on just under 10k health before i spent 10 attribs into phys for gear,
which would’ve pushed him over 10k.
And the direct link to the 2nd patch of the updates as it’s a pain to find in that thread otherwise.

It has been added to the OP 
It’s still abit too much health gone imo, 1/3 of my total health removed,
when i’ve barely survived bossfights with a few hundred left.
Any removal of health will lead to more deaths.
Enemy damage as been reduced dramatically. If anything, it’s probably easier than before.
I’m in the same boat my Spellbreaker is more of a glass cannon build not much defense at all. I had 7900 health at level 61 and after the patch(es) I now have 900 less health.
Get 40% dodge!
I have ~5k hp at 81 lvl 
The thing is though, regardless of what the numbers say… how does it feel in game ???
As reading a single number means nothing when you have no incoming damage to base it against, as it’s not just the player char that gets tweaked, the mobs do as well. So without actually playing and ignoring the change in that one final number to see how it plays, it’s all just a guess as to how it will work.
Equipped my first two legendaries on my Spellbreaker and what a difference they made. My chest was a pos level 49 crafted item which I dont need the attritubute reduction anymore. Replaced it with the Shroud of Illusion … so much better I’m back up to 7500 health.
Dumped one of my crafted weapons for a Beacon of the Winter’s Veil w/ a Shard of Beronath. Much better dealing with Elites and Bosses when Beronath’s Fury is at full charge.
Somehow I still need to complete Black Heart of the Void despite what I thought was a full clear in BoC.
