Yes, vulturing. It's your interpretation of that word that makes you think it's bad. Ran made a fortune vulturing. It's neither good nor bed. Just sayin', most planets have control, so you won't be able to slab anyway when the random empty ones disappear. If you're at someplace like Cirrhugrin, then best of luck beating out the 50 other homeless people trying for those slabs.
Otherwise, try making friends who already have planets and arranging a home there.
"I like Justin Beiber Mash-Up's the best" is what I keep telling myself.
It is common knowledge that combine implementation rarely goes to plan, the first time a new feature runs it can generally be assumed that it won't work. That is the nature of the games development, suggesting it is to benefit any one party over another is ridiculous as if that was the case the feature would never have even been implemented in the first place.
Fact is that the vast majority of those slabs that will decay are simply slabs on secure planets that people had better things to do than save. Any chance of people managing to lay a few slabs due to decay is completely and utterly insignificant. Even if the opportunity to seize meaningful control of the planet occurs it will be contested in a manner that makes the slabs useless. That is, useless until the faction you just annoyed can simply vaporize you and those slabs in the future (that's the place where the consequences of your actions catch up with you).
If you seriously let SWC effect your real life to such an extent just for that you need to stop playing computer games, or at least play one you're good at.
