battle for azeroth

It's as simple as that. How do we get to Tiragarde Sound at 10. Blizz said we have access to it starting from Level 10 but the Boat that normally takes you there from Zuldazar isn't interactable at 10. I never played BfA so it's probably a stupid question.

Does anyone, regardless of character level, have the ability to check an epic weapon vs a blue / heirloom / green weapon of same ilvl and corresponding weapon category on BFA beta/ptr? I am curious as to how the stats look like, whether the epic actually holds any value over the others.
