I'm not sure what everyone in this topic are arguing about, but it's an indisputable fact that every tank pre 30(pld pre-40) is putting out around 10% less emnity than they did before regardless of what there gear, vit/str or playstyle was before, with even less from 15-19 due to how the tank equipment stats are at those levels. That said I haven't done any leveling dungeons with any of my tanks below brayflox since the change, so whether or not the change makes it impossible to hold agro against a good blm in the early dungeons I have no idea
