Movement with wings(currently):
Ground: Normal walking speed
Slow sand: Normal walking speed
Shallow water: Normal walking speed
Deep water: Slower than swimming without wings
Ocean water: Speed like walking in slow sand.
Like Ryjofa Rage* ment, why are they slower in deep water?
I'm guessing it shouldn't matter too much because the wings do allow us to walk on water yet it is quite annoying since you are now slower on deep water.
