As part of the emergency update completed last night, a change was implemented that increases the amount of damage done by someone wielding a 2 handed weapon.
This change was made due to a statistical imbalance in the way that damage is calculated at the mid-to-upper levels. A person wielding a one-handed weapon of a given ratio was able to do more damage than when wielding a two-handed weapon of the same ratio.
We would like to stress that no change has been made to the amount of damage done by people wielding one-handed weapons. The net result of this change is that people choosing to wield two-handed weapons will now do more damage than they did before.
