Greetings,
1. http://www.wowhead.com/strand-of-the-ancients
2. How it works on Pandawow: Players teleport from the ship to the shore which gives the opposite faction the advantage to set traps, CC, et-cetera..
3. Cross realm (tested today 8/16/2017)
4. 10/10 (this BG map is full of bugs, at least having this fixed will make it more viable to play)
5. How it should work:
As you saw in the video from retail, the ship was moving and arrived at the shore, not teleporting players!
