I think there has been some confusion on this subject, because a train has been and always will be when you get someone killed or run the mobs to a zone and lose aggro, shouting "TRAIN TO ZONE"
A pull on the other hand is NOT a train, IE AOE groups that PULL half the zone and nuke/stun and no one dies. I think there would be a lot of clarification to new members if you said NO PULLS larger than 10. I know I sure didn't think that was what it meant, and I am utterly shocked after playing on this server for a few months, I had no idea that this was how Hunter wanted his server to be. It completely changes the game. No wonder people are having a knee jerk reaction to this, I know I sure am.
