If you bought the founders pack - your 30 days of elite status start upon reset.
If you already bought an elite status now, in beta -- you had to buy GP first. That GP will be refunded to you, and you can buy more elite status to tack onto the end of the 30 days you already got, or you can buy something else.
Anything that you have purchased such as Elite status, Founder Packs and GP. Will be returned to your game account once we wipe the system. Which means any GP that you have purchased and used, will be accessible to use again.
So what does that mean with the Elite status that all founders get upon open beta? If we bought Elite in game, after being told we would have it from buying founder in Open Beta, do they stack together? Or does the instance with the highest duration apply and cancel the others out? For instance, I bought the Hunter Pack, which gives you 7 days of Elite Status when Open Beta hits. Now if I were to buy 30 days of Elite status now to help with the grind, would that 30 days be added to teh 7 days already promised at Open Beta, or would the 30 days trump the 7 and cancel the 7 out?
