Tier II contents after those from Divine Might (especially Avatar primes) aren't attracting people's attention. I tried forming parties for it several times, but I have always ended up soloing them myself, because no players wants to join in the fun. It seems people are not interested in papers neither, probably because they got all their papers they need.
There a couple of ways I could see to bring fruitions to these battlefields:
1. Make equipment RARE only, so they can be sold at AH (I don't understand why all these gears got to be RARE/EX).
2. Increase the drop rate on difficulties (Very Easy & Easy) when soloing it (very far-fetched idea, I know. But I really want some of these items very badly!)
3. Let the Trust NPC be able to participate on the battlefields.
If something isn't done, I would be left with my last alternative. /yelling to buy these equipment at a unreasonable price.
