About half of the wizard classes are really good, and the other half is either weak, utter trash or just too gimmicky/have limited uses.
Adding to that, many of the good classes don’t have good synergies with each other. Dark Wiz, Elemental Wiz, Summoners are more or less isolated from each other, with very few overlapping classes. (such as FF being good for both Dark wiz and Summoners)
If your wizard feels weak, I can see 2 possible issues:
- You simply don’t have the right gear/ichors. Example: Shadowmancer requires the Diffuse Reflection Vaivora to be good, without it the class severely lacks in dps.
- You tried dipping into multiple “categories” of wizards, and ended up weak due to the lack of synergies between your classes.
