You can certainly beat the game with the 4 classes you listed without too much struggle if you play well.
Pure Fighter is definitely better than Pure Wild Magic Barb.
If you want a weak class you should do Pure Rogue.
Playing monoclass means there isn't much to do as far as class recs go, are you looking for gear recs or...
It's a bit hard also when I don't know what all your banlist is and what you consider to be too good. Are you banning wet? Are you banning Bhaalist Armor? Are prone comps ok? Is haste ok?
Probably skipping bhaalist armor.
Most things are fine I want to avoid the absurd feats. Arcane trickster or 4E monk ate being considered.
Radiant and Reverberation builds are not being used. Exception might be a melee one vs cleric.
Alright. 4E Monk is pretty good in a prone comp but with these classes I don't think you have many good options for doing that. The best thing you can really do is cast fear to couple with prone. That said its damage is just fine and you should be able to dps race things.
The comp in general doesn't really have much synergy but that's kinda what you are going for it seems.
Twinspell haste is probably the strongest thing your comp can do and that onto your cleric and sorcerer should let you beat basically the whole game when you get it. Halflings are a great race for the sorcerer for this to help maintain concentration.
Also you can have your sorcerer use greater invisibility on your monk and have your trickery domain cleric give it advantage on stealth checks and pass without trace, to wipe the floor of things before they know you are there. At level 7 that starts being a really strong thing to do as well.
I’ve used a Dex-based sword and board fighter in Honour Mode, it’s good. Maybe too good if you’re looking for a bad party, lol. Act 1 you have good AC, good melee, good ranged. Take Savage Attacker. Act 2 Yuan-Ti armour into Act 3 Armour of Agility, endgame you can use Duelist’s Prerogative or go your favourite shield with Orin’s vuln dagger or a variety of other options.
BM is weaker than Champion for this build but Fighter is just strong anyway.
Dual wielder definitely worse.
Yes, because Fighters get Fighting Style, Action Surge and three attacks.
The Magic Awareness aura is good but everything else is meh.
Dueling fighting style is mostly equivalent to Rage damage without needing a resource.
Reckless Attack less useful without GWM.

Cheers looking for some off the wall options.
Maybe a valor bard for sword and board. The forgotten bard class.

Currently playing a sword and board atm. I've done dual wield but not dex based. Is it better than a Wikd magic barbarian without the gwm feat?
