This game really needs some sort of reconnect button, numerous times I have been disconected during an instance and been booted out and had to zone back in and walk all the way through the instance again, this is especially annoying in explorables that dont have any waypoints and have traps along the way (perhaps another idea to add more waypoints) Further to that I just got disconected in the new fractal of the mists dungeon and I was the leader of the group, It decided to boot my entire party out of the instance.
Please fix this it has been a problem since release and was a feature in guild wars 1 anyway.
