I've mentioned this in a few other threads over the past several months, but I feel now that the reveal is tomorrow, it's worth reiterating and potentially starting some more speculative discussion about it. We need to talk about boats.
From a confirmed internal source I can guarantee you with 100% certainty that 8.0 is going to introduce a lot of water-centric content. We are going to spend a great deal of time on boats. These will not just be for travel: both PvE and PvP combat will take place on your boat (and/or maybe between players on multiple boats?) It is not clear if everyone will always exclusively man their own boat or if parties can share a boat or what, but - trust me, as ridiculous as this may sound - this expac is going to be very heavy on open water content with boats as your primary mode of personal transport.
There is also new engine tech to make the surface of the water more interesting, including physical waves. I do not know if or how this will be relevant to gameplay in any way beyond aesthetics, but I'm sure we'll see soon enough.
I wish I could tell you more, but mostly I'm interested in other peoples' ideas of how this could possibly make for a good expac. My initial reaction upon learning about it was basically, "oh god that sounds terrible," but I've been reassured that there's lots of good stuff here.
Thoughts?
