The health of the game can be seen in the vendors npc, since the lock mechanism/group reduction there's been a steady decline on the variety being available to purchase, coincidence but it seems like the game population has decreased. Lower level being cast out of high level dungeons it's a normal occurrence this sets a chain reaction that's hurting this game because people going to quit after failed attempts to participate at getting better equipment to improve inventory to keep up with the leveling curve. What we need is a system that has ability to change the numbers for the dungeon let's say 6 lv 70, 5 lv 70 2 lv 60, you can fluctuate a group from 6-10 people based on their level.
Before you had lower levels "leeching" now the lower levels are being outcast.
