The problem is, at rank 2 or rank 3, your wizard actually has a lesser dps than cleric and swordsmen.
Try leveling to rank 4 and you will understand the pain of playing a wizard (low dps, high cast time, not enough sp, mediocre CC).
If they are going to revamp the boss, they certainly need to balance the class in ToS first. Some class is not well suited for fast pace battle as for now.
