Q:
Guild Hall Nodes Questions!!
A:
Nodes with the same upgrade level share an ID for the purpose of cooldowns.
If you have one hall accessible with full upgrades, and one that’s missing an upgrade, you shouldn’t upgrade the missing one, as (at least until Anet fixes the system) you will be able to harvest both halls.
Thing about it like rich or static nodes. If you take a rich node on one character and go back with another it’s used, even if it’s a different map instance. If you go to a different node you are allowed to use it. However, if you go to the same noral node on 2 characters you can hit it again, or even the same node in 2 map instances.
The guild hall nodes track for your account as entities, rather than relative to the map. They work like rich nodes, but each level of upgrade for those nodes is a different entity. So, if you have a fully upgraded ore node, gather it, and then apply an upgrade to ore nodes, you can instantly gather it again. The same thing applies to multiple halls. The level of upgrades doesn’t matter, but if the nodes have, individually, different upgrade levels than you can harvest both because the game considers them different entities.

You can harvest from both if they are at different Synthesis Output levels.
