What the heck are these?

[Potpie]

I am pretty sure I only see these when I'm playing my rogue - my gut says some Ace2 addon is doing it, but I'm not sure.

Can anyone tell me what the little aqua floaties over the heads are for? Thanks!

:) That the icons you were talking about the other day? Interesting! Never seen those before. You have a list of what addons you're using?

those are mobs that detect stealth. that is what the icons are for.

Thwak beat me to it. You will only see them while you are stealthed (druids, rogues, or those with the cape).

OK - so they are part of the Blizzard UI.

Cool, thanks guys!

AAHhhhh, thats been bugging me for a while now. I always assumed it was a glitch that would be fixed in and upcoming patch or something. Good to know, now I'll stay extra far away form those mobs.
