You can ‘fix’ POS’s by duplicating/recreating them under the new structure coding/rules though. Make a new structure class. Call 'em small structures. Hey, call 'em FOB’s, or staging structures, Deployment towers, or whatever. Something to that effect. Put 'em on the new access list system and then make the hangars basically like access listed mobile depots.
I get that the old POS code is a disaster and Eve needs to be re-coded from the ground up because it’s broken. But there are ways that it can be worked around. Might break a few things, but hey, when has CCP changed anything in Eve that hasn’t broken something for a month after?
I didn’t know the old guy was hit by a bus, but no, I wasn’t going to suggest trying to lure him back. The only thing I wouldn’t be sure about would be the bubble itself, but if worst comes to worst, you can always replace it with tethering, though that’s less ideal.
There’s probably at least half a dozen other ways that structure spam could be moderated, especially out in null sec, that could all be controlled through the system management side or maintenance cost side.
A couple other quick ideas off the top of my head that other people have put forward would be degrading structures in hostile space when not maintained, entosising structures to have various effects, adding more gunner positions and fitting options to structures to require more than just one dude in a gunner seat, decoupling the actual offensive mods of the structure to similar batteries like POS’s had, siphoning off fuel from hostile structures in your space similar to the way the old siphon units sucked away moon goo, expanding the actual defensive fitting options for structures like bulkheads for example, or even doing something really crazy like system effects based on the Ihub(or your own structures) that could tamper with hostile structures in space. I’m sure there are several dozen more, too. So many of these would be better and more interesting solutions than this, though, and they wouldn’t so heavily stack the deck against the smaller side.
I will link back to this again because I feel it’s well past time that people stop and re-read it and understand that yet again, we’re at this point where a set of proposed changes is about to deal immense damage to part of the community and CCP is just barreling forward. EVE Online
