You said dual melee weapons, hm...
How about a "Huana Mataru" Unbroken/Wizard with a spear (Stalker's Patience) and a club (Kapana Taga) plus Reckless Brigandine plus Whitch Mask (later Champion's Helmet)?
Sounds weird? Let me explain:
Unbroken have a nice passive that grants them a big bonus with Engagement/Disengagement Attacks: +1 Engagement and +10 PEN on diseng. attacks. Paid for with -10% Stride (nobody cares once DAoM is active) and -15 Reflex (counter with a self buff like Llengrath's Displaced Image if you must).
Kapana Taga has the will reducing modal (-25 Will), dual damage (crush/slash) and neat enchantments - one that gives you +2 engagement. You are at 3 engagement slots.
Stalker's Patience has a modal that gives you +1 engagement at the cost of lesser stride (again: DAoM), it does awesome damage due to the wounding enchantment and you can skip recovery on crit 20% of times (cool, especially with disengagement attack which have high ACC bonuses, also with Overbearing Guard). You are at 4 engagement slots.
Reckless Brigandine gives you more dmg, AR and action speed based on health and/or on how many enemies you engage. That stacks with Mob Stance(!). You are at 5 engagement slots.
If you take Hold the Line you'll get 6 engagement slots (not really needed but maybe good to gap the bridge until you get all the items).
With Reckless Brigandine, Armored Grace, the Pet Abraham, dual wielding, Two Weapon Style, DAoM and Mob Stance you will be pretty fast, especially once you engage a lot of enemies.
Now... White Witch Mask, why? It gives you +1 to all Illusions (and looks good with Kapana Taga/Reckless Brigandine and thus completes the "Hauna Mataru" look quite well).
Illusions include stuff like Dazzling Lights, Miasma of Dull-Mindedness and the two terrifying Ryngrim spells. Now the Unbroken and Wizard parts come together:
You gather enemies around you and engage them. You hit them a bit with the club+modal (-25 Will). You cast Miasma of Dull Mindedness onto the enemies (-40 Will -> now at -65 Will). You cast Ryngrim's Repulsive Visage. Now the enemies get terrified and try to disengage. Often they trigger hefty disengagement attacks which will be executed with Stalker's Patience (chance of skipping recovery). If they die you will get an additional Full Attack from Mob Stance. And so on...
Disciplined Strikes + Merciless Gaze lead to a good amount of crit conversion.
You can really mess up enemies that way, do CC and damage at the same time. And against fear immune enemies? Well you are still a proper Battlemage so you'll think of something.
The most fun part imo is that if you summon an Essential Phantom it will also have +3 engagement from the Brigandine and the club. So you can both deliver disengement attacks. It won't have your modals and passives but it's still a nice addition.
If you want you can even summon Concelhaut's Draining Touch and use it als main weapon instead of the spear - but in order to keep it you need to use a game glitch. But even if you don't want to use that glitch: on a phantom the Draining Touch weapon stays after hits and will not dissolve like if would on your own character. And the neat thing is that it has not only huge base damage but it targets Will instead of Deflection (and you reduced enemies' Will substancially before).
Icing on the cake is Zandethu's Draconic Fury (spell from a unique Grimoire) at Power Level 7. It lets you terrify on hit and getting hit (and adds two potent lashes). Too bad it's on the same tier as Wall of Draining - so I'd recommend Bloodmage in order to gain that spell use back so you can cast both spells in one encounter.
I didn't play this for a whole playthrough though so I can't say if it's fun all the way. I only verified the concept with a hireling during a normal playhtough and with the console + some random encounters. But I always wanted to play that concept.
