No need to skip cutscenes. I got through it in 2 days. The first day was a pretty big 18h time sync. And then on the next day it was slightly fewer hours. Overall it amounted to about 30+h. And I did almost all the blue aether current quests and some other unlocks. The people I know who skipped the story got through everything on day one and had all crafters/gatherers at 90 by day 3 or something.
