In addition to what EP said damage is not hard to get... There are already many was to drastically increase your damage which has helped make armor sub par. The lack of ways to increase attack has kept defense in a dominate position couple that with what has been previously stated about attack reducing buffs flinch+fumble and dispel curse it makes it very easy to unresolve combats.
I too would like to see avenger be changed to effect attack.
I agree! However when it comes to flinch and fumble receiving possible adjustments, I would like to see fumble take most if not all of it as it is a PvP only buff. This would allow Flinch to remain effective in other aspects of the game!
