It all depends on what class i am and as well what im going after as well. i usally play Mystic Knight or magika archer. for Knight i like to have a Ranger and a strider and a warrior. you could swap the strider for a magic class. When im an magika archer i use 1 ranger or strider and a fighter and a warrior. i tend to ignore the magic classes but they can be handy in some situations.

As a warrior you need to play the tank role, so it's a good idea to get a few ranged DPS pawns.

Ranger's a good choice, but 2 is one too many. Depending on the area where you gonna wander, a strider might be a better choice (strider suck in spaces with low ceiling, because hailstorm volley and fracture dart dont work there, it's better anywhere else).

A support mage would be a good adition. Though pick one that has holy affinity, spellscreen and grapnel.
Healing and curing spells are no good, prefer healing item (and dodging damages). You can order it to use his support spells (affinity and spellscreen) by calling for help.
Most important inclination for a mage is medicant (this tell pawns to use support instead of trying to attack ennemies).
Give it a Legion might (black cat staff) and you'll have a very convenient main pawn (this staff automatically revive said pawn after a few second, so you dont have to baby sit them against dragonkins, they still get sent to the rift if their body is destroyed tho...).

If you can easily keep the agro from ennemies, a couple sorcerers is a no brainer choice. They'll have plenty of time to complete their casts while you keep ennemies busy.
They'll need to have utilitarian, challenger, mitigator inclinations, in that exact order, and the same nuke spellls (best combination being bolide, glicel, fulmination, all at the basic tier for faster cast and no tier conflicts).
You need at least 2 so they can synch cast together.
It's a good idea to have at least one with necromancy (base tier too), this spell is very usefull in BBi and you can make them cast it on command with the "Help" command outside of combat.
Then you need to have one with Voidspell, also very usefull in BBi because of the leapworms and petrificating ennemies.
Dont bring sorcerers with holy affinity or any affinity for the matter.... they can tuse it in combat because they dont have support inclinations to do so, this will be a waste of skill slot.
Dont take sorcerer with maelstrom.... you cant play your warrior if you cant see the battlefield....

Being a warrior, I dont recommand bringing a fighter or another warrior along....


TL;DR: 1 mage or one ranger or one strider, then 2 sorcerers.

my team composition for beating the whole game was summoning level 200 pawns right at the start for 0 cost because my friends completed this game years before me lmao
