What problem? Are the structures preventing you from doing something? It’s super easy to define something you find distasteful as “a problem” but it’s also super lazy and doesn’t actually make it a real thing.
You can do something about it if it bothers you. Just making it a free for all isn’t fixing anything. How many structures are even going into abandoned right now? Will they even be there in two weeks? Would this change fix the “spam” or are most structures actually fuelled? People that want to sit in their PvE ravens for half an hour at a raitaru already can. They just have other things they want to do with their time.
Those that want in on the abandoned state piñatas have already gotten themselves into a position to participate.
This isn’t going to solve any problems. If you wanna change the structure landscape there are Corps you can join or you can start one.
