I've made "warning" signs for Line of Sight / Out of Range / Not Behind Target for weakaura 4.0.0 (Bunny67 backported one)

Basicly when you cast spells/skills that are either out of range or line of sight it will pop up warning message for 1 second.
Same goes with when trying to shred as a cat but you are not behind.

Here's how they look like:
