On the community update thread linked above, a user said:
This is all good stuff. But is GW getting fixed anytime soon. I feel like the devs addressed the GW issues and it's going to just get buried over time. Is there an ETA for a fix?
dev 'swivelmaster' responded with:
We're working on it. Can't give you a decent ETA but we've got stuff to test internally next week. It's not as easy as you'd think since it deals with PvP matchmaking opponents and is somewhat random.
