My voidwalker and voidlord had 238,000 and 282,000 ish respectively. On patch day my voidwalker now has 186,000 hp. This does not factor in shadow bulwark which would temporarily put my voidlord over 300k; which no longer does.
The character remains at 402,000 hp so that source for pet HP (some of it is "off of" your own) is unchanged.
Did the major glyph of demon training stop working? I was under the perhaps mistaken impression it buffed the health of all the demons? Or is it supposed to only buff that of the Felguard; which also now has a less than spectacular health pool.
Was it bugged before? I hope to hell that was not the case. I remember noticing my pets had more HP than those of other locks without the demon training glyph; but their character HP was in the same ballpark as I.
I like the larger health pool on the pets in addition to the now more useful pet heal (I can out heal most damage they take) as I like to greedily...greedily mind you; pull more than a few mobs with the blue berry to move the questing along. Years past; that pet heal was pitifully insignificant.
I've looked in other non blizzard forums, did searches...no one else has mentioned it that I've found. I can't be the only one. I also tried dismissing and re-summoning.
I submitted a bug report but /shrug
