Old Lion's Arch (Memory of Old Lion's Arch) should have the original vistas and points of interest back. Also some services like guilds services, Guild Banker (bothe in the bank) and a Weaponsmith vendor next to the Armorsmith vendor in Trader's Forum are missing too. They were also in Old LA before it was destroyed. Last but not least, the area names are missing on the map too.
It would be nice if they are re-added in the next patch.
