In what way do  you think it's broken?

It has been heavily modified since beta 1.  I personally like it. A lot. There are other weapons that do massively more damage in 1 hit than Maul can do in several hits.

It needs to subtract a percentage instead of -4 each hit. I have a unit with 46 accuracy that can do too much damage with it. It pales the other weapons options still. And for that matter, it should be priced way higher. Currently it does better damage than lots of late game weapons and is only worth half the price to sell. 

yeah but the problem is with low level things like bear (Even if on monster i can accept a powerful ability) and the first hammer with maul

i found couple weapons with very good dmg but still on low mid level with a random crap maul and few accuracy you can literally 1 shot too many things and there arent other weapons able to do so unless with a lucky crit

Aside from very early game maul on a bear is irrelevant.  Early game when you have three guys with spears or a level 2 hero with a club a bear SHOULD be dangerous.  

From my experience (in .85, sorry haven't got a chance to tinker with .86 yet), My lvl 7 Sov can do between 30-80 damage with the maul one hand axe.  This axe does not decrease initiative.  Each hit doesn between 5-10 damage.  The bigger weapons that can do larger one hit damage seem to always reduce initiative, therefore getting less attacks in.

Would it be possible to have a seperate module for just battles that we can pick what units and equipment are dueling it out, and then play the battle to see how things pan out??  Would solve the maul debate.... and let me find the best combination of weapons and abilities

I have a Berserker's Axe with level 7 requirement in my current game and it has never hit any unit more than once in the whole game. It misses the second attack every time no matter what I'm attacking. Since it usually only does 7-9 damage on it's single attack and since the tactical combat freezes for minutes at a time every time I attack with it, I finally quit using it in disgust.

So, Maul is now either bugged, useless or both in 0.86.  Too bad since I didn't get into the beta until now and get to see what it was like before it was nerfed into oblivion. It sounded like fun.

I have survived bear cubs in 0.86.

And no, I havent hacked!
