As someone who’s lost stuff to asset safety I can say truthfully “don’t fly what you can’t afford to lose” or “don’t be daft enough to store all your stuff in a destroyable structure”.
All citadels no matter what they’re used for were made to be destroyed, you know that when you put all your stuff in there.
I’ll be honest here, I really don’t know why asset safety exists, everything should be at risk of being either destroyed or ejected into space as containers or as salvageable wrecks, and I mean everything from a humble Shuttle BPO to multi Trillion isk Titan BPO’s.
If you can’t defend your Keepstars that’s your alliance issue and when it goes down it should all be up for grabs.
Nor should anything change because you’re away on holiday or training, that’s your choice and you know and accept those risks.
