It think that not! Lets think in tibia like a RPG, if i'm a knight "Low lvl". And i hunt in dark catedral, some bandits, some monks, etc, ¿why I have the power to control elemental attacks?, Knights fight with a sword, a club or a axe.
Its right, the Knights of club dont have something like a fire sword or a fire axe but, its neccesarie?
if the reason to create a new elemental mace its "To fight with ghosts", why dont use avalanches.
Cipsoft can use that recourses to another thing that can me better for more players.
Also Knight of club now have the Falcon Mace that hit with Energy
