If you weren't happy with WoD, do not preorder whatever X6 is. Simple. Obviously you could not buy the expansion period, but if WoD did not satisfy you, protest/vote with your wallet. If there are not enough preorders, they will know they aren't selling a good enough product. People have been saying this for a while now, but it's a good business practice in general. If you're concerned about quality, wait for reviews.
