So I've noticed there are a ton of different icons that can appear above players' heads and monsters' heads. There is a guide out there already:

However, there are a couple of questions:
- The [!] icon can appear above monsters as well, what does this mean?
- There are icons that are not documented in the image above:
-- There is a "flame" looking icon. It first appears yellow, and then red. The monster's health bar border also turns a glowing red. This only appears on normal mobs and not BAMs in dungeons. What is this?
-- There is an icon that appears above mobs (not specific to dungeons) that looks like an antenna, like the one you see on cell phones to indicate signal strength. Whats this?
