Since the Markarth DLC came out I've noticed (and been annoyed with) the fact that my player health bar no longer shows certain visual effects that it used to. These effects pertain to Major/Minor Resolve, Major Breach, and Major Brutality. I'm sure there are more, but I haven't properly tested them...however on my Stam DK I've noticed these 3 not showing up (not showing Major Resolve and Major Brutality on my health bar, and not showing the Major Breach cracked texture on enemy health bars). I'll try to show what I mean below visually with some images.
Visual appearance of Major Resolve on the player's health bar:
Note, this effect is still shown in the Markarth patch, but only after roll dodging if you have the 'Phase' passive enabled in The Steed tree in the Champion Points system.
Failure of the Major Resolve visual effect on my health bar after immediately casting the DK skill Hardened Armor. It shows the Damage Shield (purple outside the bar) but not that "armored" effect around the health bar found above and the same effect it used to show prior to the Markarth patch.

Visual appearance of Major Brutality (prior to Markarth patch). This effect still happens if you have a Weapon Damage glyph on your weapon. I was able to get this effect to appear after light attacking an enemy mob with a bow that had this enchant on it. As you'll see below tho, it no longer appears when using Major Brutality in the Markarth patch.

Glowing effect after casting Rally (Major Brutality) not showing up on the health bar. Again, this glowing effect seen above used to show on the player's health bar when activating an ability that gives Major/Minor Brutality prior to the Markarth patch.

Major Fracture (now just Major Breach) used to show this cracked health bar on an enemy's health bar. Prior to the Markarth patch this used to show up when skills like Noxious Breath and Puncture were used. I was only able to get this to show up in the Markarth patch by light attacking with a weapon enchanted with a Crushing enchant.

Cracked health bar
not showing up on enemy health bars after casting Noxious Breath. This has been an annoying issue for me since the Markarth patch was released as I used to rely on this cracked effect to show me whether or not Noxious Breath was properly applied. As many know, Noxious Breath in it's cone pattern sometimes misses the enemy (it's been notoriously bad at landing for years), but seeing the cracked health bar due to Major Fracture (again, now called Major Breach) used to indicate to me whether or not the skill landed on the enemy.

My hope is that ZOS will see this post and fix it soon. I've tested a few of these on my other characters and it's not just a problem my DK is having. I also disabled ALL of my addons and tested these and the issues were still there. Hopefully the pictures I included here help make this issue clear and we can see a fix soon.
