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!

Agree with rbevejr, no need another cleric beside ranger/cleric. I suggest you to dual ranger at start (lvl7) to cleric, so he won't be too far from others in level, and he will get extra half attack, all druid spells and many weapons skills.
If you are looking for 6th member, I think you have 2 really good choices:
1. Get a blade, f/m, f>m or f/i as tank. I think blade is the best. Multiclass is a bit nerfed since they will get HLAs later. You can swap fighter to kensai/berserker if you chose dual. In this case I would swap weapon proficiencies in your group. like this (in this order to max. it):
vagrant: flails/clubs/axes/long swords
berserker: halberds/2 handed swords/staffs
ranger/cleric: clubs/maces/hammers
blade or f/m: katanas-short swords/scimitars/any other weapon

2. If you want to keep your berserker as tank (I think pure AC is not enough for tanks in IA, especially not in high end game), then I would recommend any warrior type char with 2 handed weapons. 2 handed weapons, especially halberds are really powerfull in endgame, and you can get good halberd/2handed sword at early point of the game. Or maybe you can try berserker/druid dual with spears and staves, but I think it is too big loss if you don't have halberd user.
