Lol a lot of whms need to learn how to properly use fluid aura right.
It's to push back mobs that are attacking you.
Knowing this^ if you are in the back healing and some baddie aggros to u then u have all the right to defend urself and use it to push it back towards the tank.
My fluid aura usually crits for 300ish lol!
Key points to know:
- is the enemy immune to bind/ knockback?
-where is your tank? Besides or far away from you?
-are you facing the right way so that your fluid aura shot will push the enemy towards the tanks?

Only bad whms don't use/ don't know how to use it.
Stop teaching other whms to not use it as yoshi put it in the game to be used.
