If done right, that feature alone has the ABILITY(not saying it WILL, just saying it CAN) to invigorate endgame activities. There will be almost no need to server transfer due to the lack of worthawhile activity in one's current server. Primal mount farms could be everywhere since you'll have a datacenter's worth of people to search through(reliably since duty finder is a thing for older primals...). The raiding scene could be helped slightly since cross server statics would be theoretically possible. There's other possibilities too, but I can't be bothered to list more.


The only way I can see them screwing this up is by having the feature apply to current content only with little to no lobby options. That's also how I expect them to do it too. Remember Raid Finder? >_>
