Yes, it's you.
Actually its just the nature of the systems you are looking at, and the players that are utilising them. I haven't observed any particular change in stability.
Having said that, there are a few balancing changes from the last X months that have vanished/reverted to original with EDO. Ownership of a CNB is once more a liability unless there is a station to hand in bounties.
Certainly some rebalancing since the start of July ... some systems that does appear to give a bit of benefit to the controller, others benefiting weak secondary factions, others no systematic change at all. Will depend on general activity patterns.
