I get very rapid Immune spam for certain types of mobs since v10.0.7 (i.e., the text "Immune" pours out of mobs' health bars). You can reproduce the issue on Boulderfist in Valdrakken. I'm playing a Protection Paladin, but not sure if that matters.

I want to add these images here for you to see what he is on about.
Maybe an option that disables the "immune" part being shown ?

No error code tho. this could well be that Blizzard needs to fix.

Second image is just one target, on multible targets, it is fine.
Out in the world, I am seeing these numbers come up quite regularly, can be quite annoying.

You can remove Immune flags by disabling the miss/parry/dodge/etc events.

This will not display them anymore, and might be what you're looking for.

This seems to be caused when certain mobs (possibly mobs that are immune to cc) are standing in a paladin's Consecration spell. Adding Consecration to the filter list in NameplateSCT eliminates the issue, but also prevents Consecration's damage from being shown.
