When selecting the dropdown menu, a loading screen (like when actually rezoning) appears before it opens (without having selected a new zone yet).
A 'put the whole team in the same zone' button would be highly appreciated for missions like the Tholian and Deferi ones. Having to spend several minutes just to be able to play together gets pretty annoying pretty fast. Especially with the loading screen bug.
Don't fall for the fake advertising: Guild Wars 2 contains more grind than most MMO's on the market today, not less.
