most underpowered class in game?

[Vexenu]

There are honestly no bad or underpowered classes in EQ, there are just bad classes for specific styles/preferences of play. Wizard might be objectively the "worst" class, but if you're the type of player who is endgame/raid focused but are kind of lazy and don't enjoy a lot of responsibility...congratulations, put on your robe and wizard hat (or maybe pick up a dagger - Rogue would be the second choice for such a player).

And Druids are also objectively pretty "bad", but if you're a casual player who just likes running around casually doing quests and buffing newbs and porting people... then you're not gonna be well served by an "overpowered" Enchanter.

You can get a lot of mileage out of every class. Just use them in their correct niche.
