Not really. There are some flaws to your logic:
- This only impacts groups that are likely to let them go dormant in the first place. If a corp is unlikely to abandon their POS (they’re active and they’ve got roles set up so several people can refuel), then there is literally no reason to artificially populate POSes left and right prior to take advantage of the grandfather clause. The grandfather clause would be completely inapplicable to such active corps. For corps liable to become dormant… it would be beyond foolish to field POSes aggressively to take advantage of the grandfather clause if a corp is likely to abandon their POSes due to high likelihood of inactivity or insufficient manpower to maintain them. If they want to field POSes knowing they are unlikely to maintain them… honestly? Let them - they can decorate our killboards.
- Do you really think Astrahuses/Raitarus/Athanors are going to last long even when fully onlined and defended? They topple over relatively easily.
- Nobody is going to start fielding larger POSes (namely Fortizars and Keepstars) if they are likely to abandon them just to take care of the grandfather clause. They are not exactly a dime a dozen in terms of the ability (or willingness) for most corps to acquire and field them wholesale. That’s flushing ISK down the toilet to field expensive POSes you know you’re going to abandon and hence all but guarantee their destruction.
In other words, this is a grandfather clause that people WON’T be rushing to take advantage of by the nature of what is changing. The only thing the grandfather clause does is make gentler a bad situation for those who were not present when the patch was released, not preserve a good situation (eg. such as retaining unlimited data plans when cell phone companies discontinued them)
Also: POS = Player Owned Structure. Control Tower “Stick” POSes are being phased out, so the term is being reclaimed for use to apply to Upwell Structures. The majority of the EVE community recognizes POS to refer to Upwell structures by default unless specified otherwise.
