Whether you see the argument is beside the point. 

The point here is, does not an equal prepped defense defeat an equal prepped attack.

Anyway, I don't much care either way, if it makes you happy, I'll just give drowned child defensive capabilities similar to the Field Emitter. (Just in  the shape of single directional shield/ward, but still needed the shame restrictions for use)  

So it wont be specifying water now. Even though that would technically make it more flexible, seeing as before it did not block the kinetic energy within an water based attack, or any debris that would have been in it.   

Oddly, The fire shields, and sonic wards were never talked about.
