Aviator does the same effect as Ironclad Flight

[(PSN)Anime__Thighs_]

So I wanted to make a razorwing really high damage reduction build and got the new Ironclad Flight augment for Titania and put the rest of the in air damage reduction mods on her but a bronze level mod( Aviator) has the same effect as ironclad except ironclad has the vaccum negative whice is fine but the thing is you can put both on together. This is a problem because one it dose not allow for a fun build for titania and 2 there is no point in using ironclad at that point becuase aviator does the same with no negative. Please take a look at this im hoping it was just a accidental mistakes because ironclad flight is a new mod Thank you.
