I think that all the steal and metal as well as all the tech that was left after Scarlet’s attack over Lion’s Arch should be used in creating stronger city this time.
I think that this time the city can be rebuild to its former glory and not made from ship wrecks that was used in re-building it last time when the whole Orr thing happened.
Scarlet’s attack was so strong that she left tons of metal and tech peaces all over Lion’s Arch (just remember the city sized Breacher and all the Watchknights)
For me it will be a complete Lore fail if they’re not all used – we can still see all the junk laying around.
I think they’re just gonna deal with LA like America’s plan for Detroit.
Wait for the expansion and just pave over the entire thing pretending it never happened.
