Some people may have stopped doing it, but if other people take their place it would still suggest there is no issue.
The goal is to find the correct balance between people doing and people not doing it. And more than that, the right people doing it and the wrong people not doing it.
Now assuming ccp intended fracking to be a group activity, then groups doing it and solo players not doing it would be fine! No issue.
But if we reached a point where not even groups were doing it, that would definitely suggest there was an issue. Or if we had a situation where solo players were widely doing it, that may suggest that it’s too easy/worthwhile. Assuming ccp intend for it to be a group activity.
