My thoughts were: "wow, loads of players must be leaving due to GW"
If it's a success, keep it going. If it's making players leave, I'd prefer if you tell us that. Or if this about something else entirely like freeing up Dev time to fix other bugs then again, please just tell us that!
Edit: two weeks isn't much time, all things considered. There won't be any drastic changes. I'm really surprised that you don't keep it running while you canvas opinions, and also that you haven't asked more specific questions if GW is making players leave
