Starting a new game, would appreciate suggestions Options

[Mongerman]

Here I am, back for another round of punishment and self abuse. Anyway, my planned party (all created) is

Vagrant (flails as main weapon, axe or belm in offhand)
Sorcerer
Wizard (what would be a good specialist class for this character?)
Berserker (main tank, using shield with longsword/1 handed crushing weapon. All AC boosting items go to him)
Ranger/cleric
Cleric

Question, is the pureclass cleric really necessary? I choose her in anticipation of all the healing I'm going to need, but it would be great if I could throw in some melee capabilities as well.

2nd, I've been browsing the threads, and I notice the once popular f/m multi class does not have a place in many parties. What happened? Are they nerfed or something?

TIA for feedback!

Easy way to get the thieving skills would be a swashy/fighter dual instead of the kensai, no casting ability and poor AC will surely make the Kensai far too vulnerable against improved melee enemies. There is plenty of good armour to go around and this character will have the bonus of a few extra points of AC from the swashy. Hp may be a problem but with high con not cripplingly so. I would as always suggest keeping the bard but Sikrets swashy mage is also a good call.
