Is there a reason they can’t have it on when no one is in it?
Why are we moving the nodes? How many servers does CCP have, how many reinforced servers do they have? I will example with one node/server, but the idea is the same with less hardware, just with some physical servers hosting more than one node.
Node 1 - keepstar - reinforced server, no matter what we do this is still be where the most action is, it gets the best.
Node 2-4 - optional objectives - (reinforced) server, these are known locations that CCP knows will be part of the fight, the grid-node is up and running from the start, pilots might come and go, but these grid-nodes stay up.
Node 5-X - empty nodes - server, these are spun-up grid-nodes waiting for some pilot action, they are set up as unassigned grids. While in warp to a currently off-grid location, one of these grids becomes active as that location, it doens’t need to be spun-up, just told what its coordinates are. If the number of active empty nodes is less than the allotted number of empty nodes, a new one is spun-up. When the last ship leaves one of these nodes, it gets recycled, wrecks written to the DB to be restored after the battle, because ship graveyards are cool, then it’s reset to an empty node.
The assigning of empty nodes vs creating a new node could even be handled in a way that it tries to guess the load the node might get: FC warps fleet to bookmark-> use empty node. guy running for his life in a pod-> create new node.
Just because normal wormholes have only one hole to any other system, doesn’t mean our special wormholes have to, give them five or ten holes between the base system and the wormhole containing the optional objective; or have a public cyno on the optional objective, either side can warp to it; there are a few different ways around it. (For the multi wormhole bridges option, they’d have to be clearly identified so you know where you will end up on the other side, and they shouldn’t require any sort of scanning to find them. (The idea isn’t to emulate existing wormholes, but to use the existing tech to make the battles better. The optional objective wormholes should also connect to each other.)
