Eh, you'll see a decrease in clear time and the same or better survivability. Why? Simply because it's DW and you can only hit one target at a time. As Nobody said, you'll need a rapier to make it worthwhile, the Penetrated Armor, parry and off-hand strike are better than bleed and low accuracy you'd get with an axe.
I'd recommend selling or auctioning the club and buying either better armor or katana (Even though I know you're mainly trying to rely on yourself), since you plan on staying with Niten. Better armor will never hurt, katana could be a lost investment if you later on decide to switch. There are a number of options when it comes to auctioning, you could either auction it off on yourself, or give it to one of the people who host the weekly auctions. They'll take 10% of the final price but you won't have to update it yourself (and might get more attention aswell, but since this is a legendary club that's not a problem)
Yeah I tried some DW but I'm not happy at all with the clear time and this won't do as I'm still in XP mode for a long time.Well, soon I'll have to DW to work on my DW proficiencies for my future Niten but it's a waste.
I'm not so sure about selling myself as I will only have this weapon to sell so my topic would be garbage.But I don't think I was that lucky since it's only a 1h weap with no void damages.
The best would be to trade it directly for a Katana or Armors but people might try to scam me since I'm not so sure what's good and what isn't.
