Just move the MnM to the DA, it's been rule controlled into a DA clone now.
Most players don't want to learn ACM and they don't want to get into fights they have no chance of winning. They are not paying Hitech for that. In furball groups of similar skill sets, they will fight each other happily all night. Once the dueling sharks find out about the weekly party and start slaughtering the seals, the seals leave and the sharks go back to complaining about the lack of fights in the game and the DA. You are being avoided by choice because it's their $14.95 and they don't get any fun out of being your whipping posts for several hours.
The once happy group of "skill less" seals vote with their feet once DA monsters show up to take the fun out of their furball. That has ever been what happens in this game and to a degree why WT has a player base. As long as players like yourself are a random negative thing to get slaughtered by occasionally, and not an all night suicide fest, the seals are happy to play in the MA. Once they are trapped in a small air space like MnM and cannot get away from you, they leave.
I am amazed after all of these years that you guys never catch on, you are victims of your own success.
