Taxi people in?
The megaserver system likes to spread players prertty thin. This is fine – usually – but the new zones require much higher player density (than ANet seems to have anticipated)
I’m hoping the system will be changed to put new entries into more populated maps rather than creating new instances. If it happens, fewer people will feel the need to taxi as the maps will already be so well populated, and the chance of you winding up in a map players are emigrating from goes down.
