And this is an issue in itself, It shouldn't be the case that the gear with the highest stats / ilvl in the game comes from quite literally ONE location each patch cycle. I have already said earlier in this thread that we need a variety of content to offer up that sort of gear, not just one type of content at a time, whether it be multiple types of raids or even a raid that works in tandem with crafting,
a system like this one would work quite well.
This isn't a solution that needs to be one or the other, there are tons of ways to make various methods of high level gear acquisition desirable without sticking the best of the bunch in one raid for 6 months and calling it at that.
