The reason why Campaign, Reives, and Empyreans are all comparable is because they are all systems which are only successful systems when the entire community or a large part of the community feed into them in some way so that they may thrive. For instance it is near impossible for a small group of people to truly make a strong and lasting affect on Campaign or Reives, the same is said of Empyreans, no small group can easily farm hundreds of thousands of plates so that the server's Empyrean Weapon wielding community can actually upgrade their weapons from 90 to 95, it simply will not happen.
As I explained in my last post a single Empyrean weapon would take roughly 185 kills in optimum conditions, which would take a total time of around 15 hours. This is counting in 18 people fighting for 15 hours straight for a single weapon to be upgraded. Now you can say the community is supposed to work together and supply it within the economy and people will buy plates and we will all sing & dance happily, but that just won't happen and we all know that, it's why no one does VW right now even though its easier than it has ever been since its release. If that mentality did work, people wouldn't be here complaining about it in the numbers they are because it would be a non-issue, but that isn't the case, and anyone who wants an Empyrean 119 has at very least 15 hours of work cut out for them, or they have to try buying every plate they can from the extremely limited supply of them that exist on any server currently.
