I see a lot of discussion of whats the most powerful of this class or the other, or what the most powerful powergaming class is.
What about, the weakest classes? Whats the worst possible multiplayer party without repeating any classes? Note I'm assuming that after selecting the class you still try to make the character optimised- obviously all 3s is going to be the weakest possible in theory, but thats not very interesting.
You can certainly beat the game with anyone (vanilla, anyway) but it might be an interesting challenge, as well as an interesting discussion.
For me, I think we are essentially looking at a party of the weakest single class warriors.
Beastmaster- Gain almost nothing, lose most of the best weapons
Wizard slayer- Nice special abilities, nowhere near worth losing almost all equipment
Monk- better than the above but still far from fantastic
Kensai- great damage but theres a reason this is normally used for dual classing
Archer- Great in BG1 but not in BG2, and deprives the party of a proper tank
Stalker or bounty hunter? -Still no tank, though both bring some nice abilities and will probably be the standout character...
I think this would be a challenge in BG2, and in BGEE a couple of these will be awful. Just for BGEE subbing out a couple of them for thieves might have it harder, though. If its no reloads, add in a wild mage. Although that basically just reads, "if its no reloads fail".
