Warband mixes. Advice and speculation needed.

As I'm new to Mordheim in the sense of playing it. Myself and three other players are looking to play a campaign.
my question is as follows which four warbands would mix well together. I have Middenheim, Marienburg, Reikland, skaven and possesed. Looking to get witch hunters and beastmen.

My friends have no preference to warband so me giving them a warband to control is no problem.

If you are playing just for battles with not much narrative then just choose warbands that each of you like. I don't think there is much need to get a certain warband mix.

If you want to play a narrative campaign then having some opposing warbands (e.g. witch hunters and possessed) would aid the storytelling.

Also, some settings have slightly different power levels (e.g. Lustria warbands seem to be a bit stronger) so it may be beneficial to play warbands from the same setting. This isn't a problem if you stick to the standard warbands and shouldn't really be a problem overall of you don't have power gamers.

For a story-driven campaign, one of the human mercenary bands (Reiklanders, Middenheimers, or Marienburgers), Witch Hunters, Possessed, and Beastmen create two very distinct "factions" for multiplayer games.

Since Middenheimers are followers of Ulric and not Sigmar, I'd probably go with one of the two other mercenary bands...

They're not perfect, but I think the warbands in the core rulebook are pretty well-balanced - so I'd suggest a mercenary band of your choice, Witch Hunters, Possessed, and Skaven.

Beastmen are the only non-core warband, but they are still official and decently balanced, so they could easily be substituted. They are quite tough and fast, but have zero shooting.

Skaven have a bit of a bad reputation for being powerful - they do start strong, with 6 heroes, lots of models, and cheap shooting. But their weaknesses become evident after a few games. Since they were one of two warbands that came in the original Mordheim box, I think of Skaven as one of the most classic Mordheim warbands, so I always like to see them in a campaign.

Possessed can be a little tough starting out since their heroes are so expensive (and get more so if you buy a lot of mutations), but they can become very strong if they survive early. It might be a little rough for a total newbie to start with them. With the Shadowlord being such a centerpiece of the lore, they're good from a story perspective.

For Mercs, I'd stick to just one of the 3 as they have similar choices. Any of them work. Also was included in the original Mordheim box - I've never been in a campaign without one mercenary band, so for me, it's not even Mordheim without them!

And I love my Witch Hunters of course. They're a lot of fun with rock-hard henchmen, cheap and nasty wardogs, the prayers of the Warrior-Priest, and heroes who can pack strong firepower. They're also great fun from a story standpoint, and they're the perfect foil for a Possessed warband.

I'll echo Cygnus that for narrative and multiplayer reasons, it's better if you have two "good" warbands, and two evil ones. That said, I don't think you can go too far wrong with any mix of what you listed. They are all reasonably balanced and bring a variety of playstyles to the table.

Guys thank you, this forum has been so helpful for a newbie like myself and browsing around older posts you can't help but get inspiration.
I haven't decided yet on which warbands but I have a better clue now.

Also good news I went to my local boardgame shop today and to my surprise there I found a old mordheim veteran running the store who now wants in on our campaign. We can use the store for playing the campaign.
