Yes, I ship!
First, Drastoria is a canon ship, I respect most canon ships(except Snarry, Snamione and I have some problems with Remadora, no hate though, they are great in some fanfictions).
Second, Astoria doesn't have anything against half-bloods and muggle-borns.
Third, she is my favorite person to ship with Draco.
Lastly, I really like her sister Daphne Greengrass.
Isn't that enough? I ship Drastoria.
