ANet has stated they want to make Ascended gear accessible through multiple means, not just fractals. I think a great way to implement them into WvW would be as some type of reward based on server performance.
For example, at the end of each week, if you participated in WvW (say, completed the WvW portion of your monthly) and your server won the matchup, you get a bonus chest that has a chance to drop an ascended ring.
I think this will help to rekindle the fire to get people back into competitive WvW, and would serve as an incentive without making the gear too accessible. I do realize, however, that some problems such as server-swapping to get the chest may occur and ANet would have to take measures to prevent them.
