I used to do easy dailies on a regular basis in WvW, because of the potions, and about half the time stayed a bit more, depending on the activity on the map. I also discovered a few days before the change that the weekly achievements under the WvW tab also gave potions and thought I would give it a try the following week.
Then the change happened. Since then, I haven't step a foot in WvW.
I'm not really sure if one less player in WvW, even if it was only for a few hours a week, is "working as intended".
