Just like how the whole "technically no auto attack" isn't mentioned.
It's not good to list things that an MMO that just came out listed as 'features', even if the way you use that feature may be completely different.
If a major selling point of GW2 was "No auto attack!" and "Very story oriented!", a large amount of people would do the whole "Oh yes, because that went SO well for SWTOR hurpderpswtorclone."
